摘要用Salamo型螯合配体(H2L=4，42′-dinitro-2，2′-[1，2-ethylenedioxybis(nitrilomethylidyne)]diphenol)与四水合醋酸钴在正丁醇中反应，合成了三核钴(II)配合物[{COL(C4H9OH)}2-(OAc)2Co]·C3H7NO，其结构经元素分析、X-射线单晶分析、红外光谱和紫外可见光谱表征。在Co(II)配合物中，含有两个配体L2−单元、两个μ2-乙酸酯离子、两个配位正丁醇分子和一个非配位N，N-二甲基甲酰胺分子。Co(II)络合物结构中的Co(II)原子采用轻微扭曲的八面体几何构型。此外，通过分子间C-H···O、O-H···O和C-H···π相互作用，构建了无限的层状、平面状和三维超分子结构。研究了Co(II)络合物的荧光性质和电化学性质。
Abstract A trinuclear Co(II) complex, [{CoL(C4H9OH)}2-(OAc)2Co]·C3H7NO, was synthesized by the reaction of a Salamo-type chelating ligand (H2L=4,42′-dinitro-2,2′-[1,2-ethylenedioxybis(nitrilomethylidyne)]diphenol) with cobalt(II) acetate tetrahydrate in n-butanol, and characterized by elemental analyses, X-ray crystallography, FT-IR and UV/Vis spectra. In the Co(II) complex, there are two ligand L2− units, two μ2-acetate ions, two coordinated n-butanol molecules and one non-coordinated N,N-dimethylformamide molecule. The Co(II) atoms in the structure of the Co(II) complex adopt slightly distorted octahedra geometries. Furthermore, through intermolecular C–H···O, O–H···O and C–H···π interactions, infinite layer-like, plane-like and 3D supramolecular structures are constructed. The fluorescence and electrochemical properties of the Co(II) complex have also been investigated.
