基于1-(1′,3′-苯并噁唑-2′-甲基)苯并咪唑的钴(Ⅱ)配合物:晶体结构、弱相互作用和荧光发射光谱

摘要

配体1-(1′,3′-苯并恶唑-2′-甲基)苯并咪唑(L)是通过苯并咪唑与2-(氯甲基)-1,3-苯并恶唑烷基化制备而来.配体L与CoCl2·2H2O反应得到了配合物[CoCl2L2] (1).配合物1通过π-π堆积作用和C-H…Cl氢键形成了三维超分子框架结构.测定了L和1的荧光发射光谱.%The ligand 1-(1′,3′-benzoxazole-2′-methyl)benzimidazole (L) was prepared from benzimidazole by alkylation with 2-(chloromethyl)-1,3-benzoxazole.Reaction of ligand L with CoCl2 ·2H2O afforded a complex [CoCl2L2] (1).In complex 1,3D supramolecular frameworks were formed through π-π interactions and C-H…Cl hydrogen bonds.The fluorescence emission spectra of L and 1 are described.CCDC:843658.
