Abstract
Mononuclear and icosanuclear spin-crossover complexes, [FeII(HL)2](BF4)2 (1) and [FeII20(L)24](BF4)16 (2), were synthesized using an asymmetric multidentate ligand (HL). 1 has a bis-chelate structure with two protonated ligands, while 2 has a ring-shape structure comprising four [2 × 2] grid moieties and four mononuclear units.

Abstract
The solvothermal cycloreversion and in situ oxidation of 1,2,3,4-tetra(pyridin-4-yl)cyclobutane (tpcb) within [CuCN] n-based MOFs were investigated. The radical mechanism for the cycloreversion of tpcb ligands was supported by capturing a 1,3-butadiene species 1,2,3,4-tetra(4-pyridyl)-1,3-butadiene (tpyb) into {[Cu18(μ-CN)18(tpcb)4(tpyb)2]·H2O} n in the presence of 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO). Without TEMPO, a furan-based ligand 2,3,4,5-tetra(4-pyridyl)furan (tpyf) was generated within {[Cu4(μ-CN)4(tpyf)]·4MeCN} n via the C-C cleavage, followed by in situ oxidation in acidic condition.

Abstract
Inspired by the stepwise addition of octanuclear iron units into mammalian ferritin, a "stop-and-go" synthesis strategy was used to prepare two microporous (Langmuir surface area, 490 m(2) g(-1); effective pore size, 4-5 Å) hierarchical materials {[Fe8(μ4-O)4(μ-pz)12Cl0.3(μ-O)1.85}n () and {[Fe8(μ4-O)4(μ-4-Me-pz)12Cl0.4(μ-O)1.8}n (), which are new members of the EO2 family of polymeric materials (E = C, Si and Ge). The secondary building units (SBUs) E = [Fe8(μ4-O)4(μ-4-R-pz)12] (Fe8) are nanoscale pseudo-spherical clusters, rather than single atoms, forming μ-oxo Fe-O-Fe linkages between Fe8-SBUs. The characteristic Fe-O-Fe asymmetric stretching mode in the infrared (IR) spectra of these compounds appearing at around 800 cm(-1) suggest the formation of approximately linear μ-oxo Fe-O-Fe linkages between Fe8-SBUs in and . We employ the concept of continuous random network (CRN) to describe for the first time the framework features of a Fe8-based amorphous materials, in which the average connecting numbers of each Fe8-cluster are ∼3.7 and ∼3.6 for and , respectively. (57)Fe-Mössbauer spectroscopic analysis provides insights to the intercluster connectivity of and on one hand and to their magnetic properties on the other, evident by a magnetic split sextet below 30 K. The combination of Mössbauer spectroscopy and magnetism measurements reveals a spin-glass behavior with Tg of ∼30 K. The hierarchical porous materials and straddle the gap between metal oxides and metal-organic frameworks (MOFs). This study may open an alternative way for the development of multifunctional materials based on high nuclearity metal clusters.

Abstract
A chiral precursor K2Sb2(L-tartrate)2 was used for the assembly of three homochiral heterometallic antimony(III)-tartrate transition-metal-oxo clusters: Mn(H2O)6[Fe4Mn4Sb6(μ4-O)6(μ3-O)2(l-tartrate)6(H2O)8]·10.5H2O (1), [V4Mn5Sb6(μ4-O)6(μ3-O)2(L-tartrate)6(H2O)13]·9.5H2O (2), and (H3O)[Ni(H2O)6]2[NiCrSb12(μ3-O)8(μ4-O)3(l-tartrate)6]·6H2O (3). In 1 and 2, the antimony tartrate dimer precursor decomposes and recombines to form Sb3(μ3-O)(L-tartrate)3 chiral trimers, which act as scaffolds to construct negative-charged [Fe4Mn4Sb6(μ4-O)6(μ3-O)2(L-tartrate)6](2-) in 1 and neutral [V4Mn5Sb6(μ4-O)6(μ3-O)2(L-tartrate)6] in 2. The scaffold is flexible and accommodates different types of transition-metal-oxo clusters due to the different possible coordination modes of the L-tartrate ligand. In 3, a two-level chiral scaffold Sb3(μ3-O)(L-tartrate)3Sb3 is formed from the precursor. Two such scaffolds are linked by three bridging oxygen atoms to form a cavity occupied by one Cr(3+) ion and one Ni(2+) ion disordered over two positions. Cr(3+) and Ni(2+) ions are located in two face-shared MO6 octahedra at the center of a negatively charged [NiCrSb12(μ3-O)8(μ4-O)3(L-tartrate)6](3-) cluster.
