Abstract
Investigation of the analyte soaking conditions on the crystalline sponge {[(ZnI2)3(tpt)2·x(solvent)]n} method using a statistical design of experiments model has provided fundamental insights into the influence of experimental variables. This approach focuses on a single analyte tested via 60 experiments (20 unique conditions) to identify the main effects for success and overall guest structure quality. This is employed as a basis for the development of a novel molecular structure grading system that enables the quantification of guest exchange quality.

Abstract
Single crystal X-ray diffraction (SCXRD) is arguably the most definitive method for molecular structure determination, but it is often challenged by compounds that are liquids or oils at room temperature or do not form crystals adequate for analysis. Our laboratory previously reported a simple, cost-effective, single-step crystallization method based on guanidinium organosulfonate (GS) hydrogen bonded frameworks for structure determination of a wide range of encapsulated guest molecules, including assignment of the absolute configuration of chiral centers. Herein, we expand on those results and report a head-to-head comparison of the GS method with adamantoid "molecular chaperones", which have been reported to be useful hosts for structure determination. Inclusion compounds limited to only two GS hosts are characterized by low R1 values and Flack parameters, infrequent disorder of the host and guest, and manageable disorder when it does exist. The structures of some target molecules that were not included or resolved using the adamantoid chaperones were successfully included and resolved by the GS hosts, and vice versa. Of the 32 guests attempted by the GS method, 31 inclusion compounds afforded successful guest structure solutions, a 97% success rate. The GS hosts and adamantoid chaperones are complementary with respect to guest inclusion, arguing that both should be employed in the arsenal of methods for structure determination. Furthermore, the low cost of organosulfonate host components promises an accessible route to molecular structure determination for a wide range of users.

Abstract
Chiral metal-organic materials, CMOMs, are of interest as they can offer selective binding sites for chiral guests. Such binding sites can enable CMOMs to serve as chiral crystalline sponges (CCSs) to determine molecular structure and/or purify enantiomers. We recently reported on the chiral recognition properties of a homochiral cationic diamondoid, dia, network {[Ni(S-IDEC)(bipy)(H2O)][NO3]}n (S-IDEC = S-indoline-2-carboxylicate, bipy = 4,4'-bipyridine), CMOM-5[NO3]. The modularity of CMOM-5[NO3] means there are five feasible approaches to fine-tune structures and properties via substitution of one or more of the following components: metal cation (Ni2+); bridging ligand (S-IDEC); linker (bipy); extra-framework anion (NO3-); and terminal ligand (H2O). Herein, we report the effect of anion substitution on the CCS properties of CMOM-5[NO3] by preparing and characterizing {[Ni(S-IDEC)(bipy)(H2O)][BF4]}n, CMOM-5[BF4]. The chiral channels in CMOM-5[BF4] enabled it to function as a CCS for determination of the absolute crystal structures of both enantiomers of three chiral compounds: 1-phenyl-1-butanol (1P1B); methyl mandelate (MM); ethyl mandelate (EM). Chiral resolution experiments revealed CMOM-5[BF4] to be highly selective toward the S-isomers of MM and EM with enantiomeric excess, ee, values of 82.6 and 78.4%, respectively. The ee measured for S-EM surpasses the 64.3% exhibited by [DyNaL(H2O)4] 6H2O and far exceeds that of CMOM-5[NO3] (6.0%). Structural studies of the binding sites in CMOM-5[BF4] provide insight into their high enantioselectivity.

Abstract
Crystalline sponge (CS) based X-ray diffraction (XRD) analysis allows for the observation of the structure of an analyte, including its absolute configuration. Herein we report a powerful analytical platform for the separation, isolation, and structural elucidation of a target analyte in a seamless way by coupling supercritical fluid chromatography (SFC) with CS-based XRD analysis (SFC-CSXRD). The efficacy of this methodology is demonstrated by the rapid characterization of regio- and stereoisomers using three types of CSs with differing tolerances to the solvents used in SFC and guest-soaking.

Abstract
This Review discusses, along with the historical background, the principles as well as proof-of-concept studies of the crystalline sponge (CS) method, a new single-crystal X-ray diffraction (SCXRD) method for the analysis of the structures of small molecules without sample crystallization. The method uses single-crystalline porous coordination networks (crystalline sponges) that can absorb small guest molecules within their pores. The absorbed guest molecules are ordered in the pores through molecular recognition and become observable by conventional SCXRD analysis. The complex {[(ZnI2 )3 (tpt)2 ]⋅x(solvent)}n (tpt=tris(4-pyridyl)-1,3,5-triazine) was first proposed as a crystalline sponge and has been most generally used. Crystalline sponges developed later are also discussed here. The principle of the CS method can be described as "post-crystallization" of the absorbed guest, whose ordering is templated by the pre-latticed cavities. The method has been widely applied to synthetic chemistry as well as natural product studies, for which proof-of-concept examples will be shown here.

Abstract
Soaking small molecules into the solvent channels of protein crystals is the most common method of obtaining crystalline complexes with ligands such as substrates or inhibitors. The solvent channels of some protein crystals are large enough to allow the incorporation of macromolecules, but soaking of protein guests into protein crystals has not been reported. Such protein host crystals (here given the name hostals) incorporating guest proteins may be useful for a wide range of applications in biotechnology, for example as cargo systems or for diffraction studies analogous to the crystal sponge method. The present study takes advantage of crystals of the Escherichia coli tryptophan repressor protein (ds-TrpR) that are extensively domain-swapped and suitable for incorporating guest proteins by diffusion, as they are robust and have large solvent channels. Confocal fluorescence microscopy is used to follow the migration of cytochrome c and fluorophore-labeled calmodulin into the solvent channels of ds-TrpR crystals. The guest proteins become uniformly distributed in the crystal within weeks and enriched within the solvent channels. X-ray diffraction studies on host crystals with high concentrations of incorporated guests demonstrate that diffraction limits of ∼2.5 Å can still be achieved. Weak electron density is observed in the solvent channels, but the guest-protein structures could not be determined by conventional crystallographic methods. Additional approaches that increase the ordering of guests in the host crystal are discussed that may support protein structure determination using the hostal system in the future. This host system may also be useful for biotechnological applications where crystallographic order of the guest is not required.

Abstract
While single-crystal X-ray diffraction (SC-XRD) is one of the most powerful structural determination techniques for organic molecules, the requirement of obtaining a suitable crystal for analysis limits its applicability, particularly for liquids and amorphous solids. The emergent use of preformed porous crystalline matrices that can absorb organic compounds and stabilize them via host-guest interactions for observation via SC-XRD offers a way to overcome this hindrance. A topical and current discussion of SC-XRD in organic chemistry and the use of preformed matrices for the in crystallo analysis of organic compounds, with a particular focus on the absolute structure determination of chiral molecules, is presented. Preformed crystalline matrices that are covered include metal-organic frameworks (MOFs) as used in the crystalline sponge method, metal-organic polyhedra (MOPs, coordination cages), porous organic materials (POMs)/porous organic molecular crystals (POMCs), and biological scaffolds. An outlook and perspective on the current technology and on its future directions is provided.

Abstract
The crystalline sponge (CS) method allows structural elucidation of a target compound (guest) in solution by single crystal X-ray diffraction through trapping the guest into the CS framework. In principle, the CS method is inapplicable to reactive compounds that break the CS framework, such as acidic, basic, or nucleophilic ones. Here, a solution to this problem is disclosed wherein an ion pair of the guest compound is formed during the guest-soaking step by adding a suitable reagent. The ion pair can be observed and does not damage the CS framework. Using the developed method, amino, guanidino, and amidino compounds have been successfully analyzed as ion pairs with sulfonic acids. Practical utility has been shown because the absolute configurations of optically resolved amine derivatives were revealed with only a few micrograms. This demonstrates that the ion-pair-soaking method is simple and expands the range of compounds applicable to the CS method.

Abstract
Structural insight into reactive species can be achieved via strategies such as matrix isolation in frozen glasses, whereby species are kinetically trapped, or by confinement within the cavities of host molecules. More recently, Metal-Organic Frameworks (MOFs) have been used as molecular scaffolds to isolate reactive metal-based species within their ordered pore networks. These studies have uncovered new reactivity, allowed observation of novel metal-based complexes and clusters, and elucidated the nature of metal-centred reactions responsible for catalysis. This perspective considers strategies by which metal species can be introduced into MOFs and highlights some of the advantages and limitations of each approach. Furthermore, the growing body of work whereby reactive species can be isolated and structurally characterised within a MOF matrix will be reviewed, including discussion of salient examples and the provision of useful guidelines for the design of new systems. Novel approaches that facilitate detailed structural analysis of reactive chemical moieties are of considerable interest as the knowledge garnered underpins our understanding of reactivity and thus guides the synthesis of materials with unprecedented functionality.

Abstract
Single crystal X-ray diffraction is arguably the most definitive method for molecular structure determination, but the inability to grow suitable single crystals can frustrate conventional X-ray diffraction analysis. We report herein an approach to molecular structure determination that relies on a versatile toolkit of guanidinium organosulfonate hydrogen-bonded host frameworks that form crystalline inclusion compounds with target molecules in a single-step crystallization, complementing the crystalline sponge method that relies on diffusion of the target into the cages of a metal-organic framework. The peculiar properties of the host frameworks enable rapid stoichiometric inclusion of a wide range of target molecules with full occupancy, typically without disorder and accompanying solvent, affording well-refined structures. Moreover, anomalous scattering by the framework sulfur atoms enables reliable assignment of absolute configuration of stereogenic centers. An ever-expanding library of organosulfonates provides a toolkit of frameworks for capturing specific target molecules for their structure determination.

Abstract
The crystallography of supramolecular host-guest complexes is reviewed and discussed as a part of small molecule crystallography. In these complexes, the host binds the guests through weak supramolecular interactions, such as hydrogen and halogen bonding, cation-π, anion-π, C-H-π, π-π, C-H-anion interactions and the hydrophobic effect. As the guest often shows severe disorder, large thermal motion and low occupancies, the reliable crystallographic determination of the guest can be very demanding. The analysis of host-guest interactions using tools such as Hirshfeld and cavity volume surface analysis will help to look closely at the most important host-guest interactions. The jewel in the crown of utilizing host-guest interactions in the solid-state is the recently developed Crystalline Sponge Method (CSM) by Makoto Fujita. This method, when successful, gives an accurate and unambiguous 3-D structure of the structurally unknown guest molecule from only micro- or nanogram amounts of the guest molecule. In the case of an optically pure enantiomer, its absolute configuration can be determined.

Abstract
This article showcases recent advancements made using crystalline molecular flasks and the widening list of prospective applications for the crystalline sponge method. This expansion has coincided with an increasing number of materials termed crystalline sponges, and a report of a predictive means of identifying candidates from crystallographic databases. The crystalline sponge method's primary application has been determination of absolute configuration, and this has evolved from the analysis of carefully chosen planar aromatic guests to more diverse identification of natural products, biological metabolites, and analysis of volatile chemical components. However with time-resolved X-ray crystallography providing arguably the most informative atomic scale insights of dynamic chemical processes, this application of the crystalline sponge method may soon eclipse structural determination in terms of importance.

Abstract
A strategy that leverages solvent effects to noncovalently trap solid and unstable liquid organic compounds within a crystalline sponge ({[(ZnI2)3(tris(4-pyridyl)-1,3,5-triazine)2]·x(CHCl3)}n) in a simple, mild, and efficient fashion for target molecule structure determination via X-ray diffraction is disclosed. Host-guest structures were obtained using third-generation synchrotron radiation, and new beamline hardware allowed rapid data collection in ~5-24 minutes. This is 40-90% faster than previously reported crystalline sponge synchrotron datasets collected by us, and approximately a 150-720-fold decrease in time versus using a typical in-house diffractometer, effectively enabling the potential for high-throughput analysis. The new target molecule inclusion method using methyl tert-butyl ether (MTBE) solvent was demonstrated by trapping (E)-stilbene, vanillin, 4-(trifluoromethyl)phenyl azide, and (+)-artemisinin (an antimalarial drug). The potential of guests to maximize intermolecular interactions with the crystalline sponge framework at the expense of attenuating intramolecular interactions (e.g., π-conjugation) was observed for (E)-stilbene. Trapping of vanillin and (+)-artemisinin elicited single-crystal-to-single-crystal transformations where space group symmetry reduced from C2/c to P1̄ and C2, respectively, and the absolute configuration of (+)-artemisinin was determined through anomalous dispersion.

Abstract
Metal-organic frameworks (MOFs) possess great structural diversity because of the flexible design of linker groups and metal nodes. The structure-property correlation has been extensively investigated in areas like chiral catalysis, gas storage and absorption, water purification, energy storage, etc. However, the use of MOFs in lithium storage is hampered by stability issues, and how its porosity helps with battery performance is not well understood. Herein, through anion and thermodynamic control, we design a series of naphthalenediimide-based MOFs 1-4 that can be used for cathode materials in lithium-ion batteries (LIBs). Complexation of the N,N'-di(4-pyridyl)-1,4,5,8-naphthalenediimide (DPNDI) ligand and CdX2 (X = NO3- or ClO4-) produces complexes MOFs 1 and 2 with a one-dimensional (1D) nonporous network and a porous, noninterpenetrated two-dimensional (2D) square-grid structure, respectively. With the DPNDI ligand and Co(NCS)2, a porous 1D MOF 3 as a kinetic product is obtained, while a nonporous, noninterpenetrated 2D square-grid structure MOF 4 as a thermodynamic product is formed. The performance of LIBs is largely affected by the stability and porosity of these MOFs. For instance, the initial charge-discharge curves of MOFs 1 and 2 show a specific capacity of ∼47 mA h g-1 with a capacity retention ratio of >70% during 50 cycles at 100 mA g-1, which is much better than that of MOFs 3 and 4. The better performances are assigned to the higher stability of Cd(II) MOFs compared to that of Co(II) MOFs during the electrochemical process, according to X-ray diffraction analysis. In addition, despite having the same Cd(II) node in the framework, MOF 2 exhibits a lithium-ion diffusion coefficient (DLi) larger than that of MOF 1 because of its higher porosity. X-ray photoelectron spectroscopy and Fourier transform infrared analysis indicate that metal nodes in these MOFs remain intact and only the DPNDI ligand undergoes the revisible redox reaction during the lithiation-delithiation process.
