Abstract
Six new pyrazolylamidino Cu(II) complexes are synthesized directly from the reactions of Cu(X)2 salts (X = ClO4-, BF4-, or Cl-) and pyrazole (pzH) in nitrile solution (RCN, R = Me or Et) at 298 K via the metal-mediated coupling of RCN with pzH: [Cu(HNC(R)pz)2(X)2] (X = ClO4- or BF4-, R = Me, 1 or 7 and Et, 2 or 8, respectively) and dichloro Cu(II) complexes [Cu2Cl2(μ-Cl)2(HNC(Me)pz)2] (3) and [CuCl2(HNC(Et)pz)] (4). Four more new complexes, [Cu2(μ-Cl)2(HNC(Me)pz)2(pzH)2][X]2 (X = ClO4-, 5 and BF4-, 9) and [Cu2(μ-Cl)2(HNC(Et)pz)2(pzH)2(X)2] (X = ClO4-, 6 and BF4-, 10), are obtained indirectly from the anion substitution reaction with Cl- ions in 1 and 7, and 2 and 8, respectively. All complexes are characterized by EA, FTIR, UV-vis and EPR spectroscopy and X-ray crystallographic analyses. HNC(Et)pz or pzH is unobserved in both the nitrile-exchange reaction of 2 to d6-1 and the anion-substitution reaction of 2 to d6-5 in the CD3CN solution. The 1H NMR results reveal that the pzH-RCN coupling is intramolecular and reversible on a Cu(II) center. The crystal structures of these complexes show diverse supramolecular assemblies through imino NH⋯anion hydrogen bonds and pyrazolylamidino pz-pz (π⋯π) and pz-Cu(II) (π⋯metal) interactions. EPR results suggest weak magnetic couplings between Cu(II) centers in the polynuclear Cu(II) complexes. The yield and rate of the formation of 1 are higher in the reaction of Cu(ClO4)2 with a 4-fold molar excess of pzH compared with a 2-fold excess, indicating that [Cu(pzH)4]2+ is the more active species for pzH-RCN coupling. The highest rate for the formation of 1 is achieved when [Cu(pzH)4(ClO4)2] is used in MeCN solution. Thus, a plausible synthetic path for synthesizing pyrazolylamidino Cu(II) complexes is established. An intermediate species, [Cu(HNC(Me)pz)2(pzH)2][ClO4]2 (1a), is proposed for the synthetic process based on spectroscopic studies and DFT calculations. The reaction of [Cu(pzH)4X2] (X = ClO4-, Cl-, NO3-, or BF4-) in MeCN solution suggests that the lability of coordinated anions upon nitrile substitution affects the rate of the formation of bis-pyrazolylamidino Cu(II) complexes.

MOFs with Open Metal(III) Sites for the Environmental Capture of Polar Volatile Organic Compounds. Angew Chem Int Ed Engl 2023; 62:e202211583. [PMID: 36468308 PMCID: PMC10108120 DOI: 10.1002/anie.202211583] [Citation(s) in RCA: 11] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Revised: 11/15/2022] [Accepted: 12/02/2022] [Indexed: 12/11/2022]
Abstract
Metal-Organic Frameworks (MOFs) with open metal sites (OMS) interact strongly with a range of polar gases/vapors. However, under ambient conditions, their selective adsorption is generally impaired due to a high OMS affinity to water. This led previously to the privilege selection of hydrophobic MOFs for the selective capture/detection of volatile organic compounds (VOCs). Herein, we show that this paradigm is challenged by metal(III) polycarboxylates MOFs, bearing a high concentration of OMS, as MIL-100(Fe), enabling the selective capture of polar VOCs even in the presence of water. With experimental and computational tools, including single-component gravimetric and dynamic mixture adsorption measurements, in situ infrared (IR) spectroscopy and Density Functional Theory calculations we reveal that this adsorption mechanism involves a direct coordination of the VOC on the OMS, associated with an interaction energy that exceeds that of water. Hence, MOFs with OMS are demonstrated to be of interest for air purification purposes.

Abstract
Dehydration of (S,S)-1,2-bis(1H-benzo[d]imidazol-2-yl)ethane-1,2-diol (H4 L) to (Z)-1,2-bis(1H-benzo[d]imidazol-2-yl)ethenol) (H3 L') was found to be metal-assisted, occurs under solvothermal conditions (H2 O/CH3 OH), and leads to [MnII 4 (H3 L)4 Cl2 ]Cl2 ⋅5 H2 O⋅5 CH3 OH (Mn4 L4 ) and [MnII 4 (H2 L')6 (μ3 -OH)]Cl⋅4 CH3 OH⋅H2 O (Mn4 L'6 ), respectively. Their structures were determined by single-crystal XRD. Extensive ESI-MS studies on solutions and solids of the reaction led to the proposal consisting of an initial stepwise assembly of Mn4 L4 from the reactants via [MnL] and [Mn2 L2 ] below 80 °C, and then disassembly to [MnL] and [MnL2 ] followed by ligand modification before reassembly to Mn4 L'6 via [MnL'], [MnL'2 ], and [Mn2 L'3 ] with increasing solvothermal temperature up to 140 °C. Identification of intermediates [Mn4 Lx L'6-x ] (x=5, 4, 3, 2, 1) in the process further suggested an assembly/disassembly/in situ reaction/reassembly transformation mechanism. These results not only reveal that multiple phase transformations are possible even though they were not realized in the crystalline state, but also help to better understand the complex transformation process between coordination clusters during "black-box" reactions.

Abstract
Among three asymmetric Schiff bases used for the synthesis of heterometallic CuII–MnIIcomplexes, the one with N2O2donor atoms yielded a tetranuclear and a trinuclear complex whereas two N2O3donor ligands produced solely dinuclear complexes. The results of magnetic measurements have been justified by DFT study.
