摘　　要：采用液相扩散法制备了一个新颖的钴配合物Co(CBA)Bpy_(2)(H_(2)O)(CBA=4-(3′-羧丙酰胺基)苯甲酸阴离子,Bpy=2,2′-联吡啶),利用红外光谱、粉末X射线衍射、元素分析对此配合物的组成进行了表征,并用X射线单晶衍射确定了其晶体结构。在此配合物结构中,二元羧酸配体利用两个羧酸根阴离子桥联两个相邻的Co(II)离子形成链状的一维配位聚合物。A new coordination polymer,Co(CBA)Bpy_(2)(H_(2)O)(CBA=4-(3′-carboxypropanamido)benzoic acid anion and Bpy=2,2′-bipyridine),was synthesized by liquid/liquid diffusion method.The complex was characterized by IR spectros⁃copy,powder X-ray diffraction and elemental analysis.Its structure was confirmed by single-crystal X-ray diffraction.In the complex,the 4-(3′-carboxypropanamido)benzoic acid with two carboxylate anions bridged neighboring Co(II)ions to form a one-dimensional chain coordination polymer structure.
