摘　　要：通过水热法合成了一种配位聚合物{[Ni(H2BCPBA)2(H2O)4]}n(1,H3BCPBA=3,5-二(4-羧酸-酚氧基)-苯甲酸),并对其进行了元素分析、红外光谱、紫外光谱、热重和X射线单晶衍射表征。{[Ni(H2BCPBA)2(H2O)4]}n属于三斜晶系,P1空间群。中心Ni(Ⅱ)和来自于2个配体与4个水分子配位,形成八面体结构。固体紫外光谱表明配合物有一个强的光谱吸收。A coordination polymer {[Ni（H2BCPBA）2（H2O）4]}n（1,H3BCPBA=3,5-bi（4-carboxy-phenoxy）-benzoic acid） has been synthesized from H3BCPBA by using hydrothermal method and structurally characterized by elemental analysis, IR speetrtam, UV spectroscopy, TG and single-crystal X-ray diffraction. Single-crystal X-ray analysis reveals that the coordination polymer 1 is crystallized in the triclinie system, space group P1. The Ni（II） ion is six-coordinated by two oxygen atoms from H2BCPBA- ligand and four oxygen atoms from water molecules, generating a oetahedral coordination geometry. UV spectroscopy study reveals that the coordination polymer exhibits strong ultraviolet absorption in the solid state at room temperature. CCDC： 837882.
