Synthesis and Crystal Structure of a Bisoxime Cobalt(Ⅱ) Complex

利用螯合双肟配体H2L(H2L=4,4′-二硝基-2,2′-[1,2-亚乙基二氧双(氮次甲基)]二酚)合成了1个三核钴(Ⅱ)配合物[Co3(OAc)2(CH3OH)2L2]·2CH3CN,并用X-射线单晶衍射分析确定了其晶体结构。配合物晶体属三斜晶系,P1空间群,由3个Co(Ⅱ)离子、2个四齿的L2-单元、2个配位的乙酸根、2个配位的甲醇分子和2个结晶的无序乙腈分子组成,其几何构型为稍微扭曲的八面体,且配合物通过分子间C-H...O氢键形成了1种二维超分子结构。

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.
