Room Temperature Syntheses, Crystal Structures and Magnetic Properties of One Novel Decanuclear Copper Cluster Based on 3-amino-1,2,4 triazole Schiff Base

Abstract: One novel decanuclear copper cluster, {[Cu10(L)8(CH3COO)2(μ3- OH)2]·(DMF)2·(H2O)5} (1, H2L = (E)- 2-(((4H-1,2,4-triazol-3-yl)imino)methyl)-6-methoxyphenol, DMF = N,N’-dimethyl-formamide), were obtained by room temperature micro-bottle reaction. The complex 1 was characterized using elemental analysis, infrared spectroscopy and single-crystal X-ray diffractometry. 1 is decanuclear copper cluster. The {Cu10O4(N2triazol)8} core displays dominant antiferromagnetic interactions owing to the μ3-OH, and μ2-Ophenoxo bridged binding modes with g = 2.126, J = − 6.81 $$\times {10}^{-4}$$ cm−1, and zJ’ = − 0.577 cm−1.

Synthesis, Crystal Structures, Hirshfeld Surface Analysis, and Magnetic Properties of Two Cu/Ni Schiff‐Base Complexes

Abstract: Two novel complexes, namely [Cu2(L)2] (1) and [Ni4(L)4] (2, H2L = 1-{3-[(5-bromo-2-hydroxy-benzylidene)-amino]-2-hydroxyphenyl}-ethanone) were synthesized through solvothermal methods at the same condition. The complexes 1 and 2 were characterized by IR spectroscopy, elemental analysis and single-crystal X-ray diffraction. 1 is dinuclear copper complex while 2 is a cubane nickel cluster. The L ligand displays two different coordination modes. One is the μ1-L-κ3N1:O1:N2 coordination mode and the other is μ3-L-κ6O1:O2:O2:O2:N1:O3 coordination mode. Magnetic studies reveal that the complex 2 displays dominant antiferromagnetic intracluster interactions between the NiII ions through the μ3 oxide bridges with g = 2.29, J = − 0.939 cm−1, and zJ′ = − 0.333 cm−1. Hirshfeld surface analysis revealed that H···H interaction was the dominant intermolecular interaction.

Synthesis, structure and magnetism of a new ionic pentanuclear iron cluster.

Abstract: A new ionic pentanuclear FeIII cluster, namely, triethylazanium tetrakis(μ2-5-amino-1,2,3,4-tetrazolido)tetrakis(μ3-4-chloro-2-{[(1H-tetrazol-1-id-5-yl)imino]methyl}phenolato)di-μ3-oxido-pentairon(III) acetonitrile monosolvate monohydrate, (C6H16N)[Fe5(C8H4ClN5O)4(CH2N5)4O2]·CH3CN·H2O, was synthesized using microvial synthesis methods and characterized by elemental analysis, FT-IR spectroscopy, single-crystal X-ray diffraction and thermogravimetric analysis Magnetic studies reveal that the complex displays dominant antiferromagnetic intracluster interactions between the FeIII ions through the μ3-oxide bridges

Syntheses, crystal structures and Hirshfeld surface analysis of (Z)-3-[(3-acetyl-2-hydroxyphenyl)amino]-2-bromoprop-2-enal and a novel ZnII complex.

Abstract: A novel zero-dimensional dinuclear zinc complex, di-μ-acetato-1:2κ4O:O'-(μ-2-acetyl-6-{[(Z)-2-bromo-3-oxoprop-1-en-1-yl]azanidyl}phenolato-1κ2O1,O2:2κ3O1,N,O6)(N,N-dimethylacetamide-1κO)dizinc(II), [Zn2(C11H8BrNO3)(CH3COO)2(C4H9NO)] or [Zn2(L)(CH3COO)2(DMA)], 1, was synthesized using (Z)-3-[(3-acetyl-2-hydroxyphenyl)amino]-2-bromoprop-2-enal (H2L), which was synthesized from 1-(3-amino-2-hydroxyphenyl)ethanone and 2-bromomalonaldehyde. H2L and 1 were characterized by single-crystal X-ray diffraction, FT-IR spectroscopy and elemental analysis. Theoretical calculations of the bond orders and excited state of H2L confirmed that there is extensive electron delocalization in the H2L molecules. Single-crystal X-ray diffraction shows that the two Zn atoms are pentacoordinated in distorted trigonal bipyramidal configurations in the crystals of 1. The thermogravimetric analysis of 1 shows that the main frame of the complex remains stable to about 190 °C. Powder X-ray diffraction (PXRD) analysis shows that 1 possesses high purity and acid and alkali resistance. The intermolecular interactions of H2L and 1 were analyzed using Hirshfeld surface analysis and the results indicate that the H...H and O...H interactions of H2L and 1 play a considerable role in stabilizing the self-assembly process.
