中文摘要：

在室温下,以2-溴苯甲酸和2,2＆#39;-联吡啶为配体,通过溶液法在甲醇/水的混合溶剂中反应合成了双核铜（Ⅱ）配合物Cu2（2,2’-bpy）2（2-bba）4.通过元素分析、红外光谱、热重测试技术和X射线粉末衍射对其进行了结构表征,同时用X射线单晶衍射分析确定了其晶体结构.结果表明,其晶体属正交晶系,空间群为Pbca,晶胞参数：a=20.619 （4）（A）,b=10.098（2）（A）,c=21.865（4）（A）,V=4552.5 （15） （A）3,Dc=1.808g·cm-3,μ=4.505mm-1,F（000） =2440.0,Z=4,最终残差因子R1=0.0583,wR2=0.1200.配合物为双核结构,每个结构单元中2个Cu（Ⅱ）离子通过2个2-溴苯甲酸根配体单齿桥联.配合物中的每个Cu（Ⅱ）离子为五配位的结构,分别和来自2个单齿桥联的2-溴苯甲酸根的2个氧原子、1个单齿配位的2-溴苯甲酸根的1个氧原子及来自1个2,2＆#39;-联吡啶的2个氮原子配位形成了畸变的四方锥型结构,分子间则通过弱的C—H…O氢键作用形成了一维链状的结构.CCDC：972827.

英文摘要：

A binuclear copper（Ⅱ） complex, Cu2（2,2＇-bpy）2（2-bba）4, was synthesized with 2-bromobenzoic acid and 2,2＇-bipyridine in methanol-water mixed solvents at room temperature. It was characterized by elemental analysis, IR, TGA and powder X-ray diffraction. Its crystal structure was determinec by single crystal XRD analysis. The results revealed that the titled complex belongs to orthorhombic with Pbca space group, a = 20. 619 （4）A, b = 10.098（2）A,c=21.865（4）A, V=4552.5（15）A3,Dc =1. 808g.cm 3,/z=4.505mm-1,F（000） =2440.0,Z=4, R1 = 0. 0583 ,wR2 = 0. 1200. In each asymmetric unit, two copper（Ⅱ） ions were linked by two 2-bromobenzoic acid ligands in bridging-unidentate, each copper （II） ion was five-coordinated with tw3 oxygen atoms of two bridging- unidentate 2-bromobenzoic acid, one oxygen atom of one monodentate 2-bromobenzoic acid and two nitrogen atoms of one 2,2＇-bipyridine ligands to form a distorted square pyramid geometry. Weak intermolecular C--H…O hydrogen bonds link the binuclear copper（II） complex into one-dimensional chain. CCDC： 972827.
