合成了标题配合物Cu(Cmba)2(Mim)2(cmba为2-氯-6-甲基苯甲酸阴离子,Mim为N-甲基咪唑),并用X射线单品衍射仪测定了其晶体结构.晶体属单斜晶系,P21/n空间群,晶胞参数为:a=0.7389(15)nm,b=2.1379(4)nm,c=0.8150(16)nm,β=112.41(3)°,V=1.1902(4)nm3,Z=2,Dc=1.582 g·cm-3.最后精修结果为:R1=0.0682,wR2=0.1740.在配合物结构中每个Cu(Ⅱ)原子分别与来自2个羧酸根离子中的2个氧原子、2个N-甲基咪唑分子中的2个N原子进行配位.形成了1个平面四边形结构.电化学研究显示配合物中的Cu2+/Cu+对的氧化还原是一个准可逆的过程.

The title complex Cu(Cmba)2(Mim)2 (Cmba=2-Chloro-6-methylbenzoic anion, Mim =N-Methylimdazole) has been synthesized and structurally characterized by X-ray single crystal diffractometry. The complex crystallizes in monoclinic system, P21/n space group with the cell parameters of a=0.738 9(15) nm, 6=2.137 9(4) nm, c= 0.815 0(16) nm,β=112.41(3)° V=1.1902(4) nm3, Z=2, and Dc= 1.582 g·cm -3, the final R1=0.068 2, wR2=0.1740. In the structure of the complex each Cu(II) ion is coordinated by two 0 atoms from two carboxylate anions and two N atoms from two Mim molecules in a square-planar geometry. The electrochemical studies reveal that redox of Cu2+/ Cu+ in the complex is a quasi-reversible process. CCDC: 778482.
