Abstract: A trinuclear Co(Ⅱ) complex, [Co3(OAc)2(CH3OH)2L2]·2CH3CN, was synthesized with Salen-type bisoxime ligand 4,4′-dinitro-2,2′-[1,2-ethylenedioxybis(nitrilomethylidyne)]diphenol (H2L), and characterized by elemental analyses, IR spectra and X-ray diffraction method. X-ray single crystal structure analysis reveals that the complex crystallizes in the triclinic system, space group P1 with cell parameters: a=0.992 80(8) nm, b=1.084 4(1) nm, c=1.360 4(1) nm, α=73.655(2)°, β=69.847(1)°, γ=73.026(2)°, Z=1, V=1.288 1(2) nm3, R1=0.054 4, wR2=0.163 5. In the Co(Ⅱ) complex, there are two L2- moieties (which provide N2O2 donors), two acetate ions, two coordinated CH3OH molecules and two non-coordinated disordered CH3CN molecules, which result in the formation of octahedral geometries around the Co(Ⅱ) atoms. And every title compound molecule links four other molecules into an infinite 2D-layer supramolecular structure via intermolecular C-H…O hydrogen bond interactions. CCDC: 780294. |
