Synthesis,Antimicrobial Activity and Cyclic Voltammogram of Cu(Ⅱ) Complex

以L-异亮氨酸和Cu(Ac)2·H2O为原料合成了铜(Ⅱ)配合物[Cu(L-ile)2(H2O)](L-ile=异亮氨酸根)并培养标物单晶。产物结构由X-射线单晶衍射确定。配合物属于正交晶系,空间群为P212121。采用琼脂扩散抑菌法测定了Cu(Ac)2·H2O,配体和配合物的抑菌性能,实验表明,Cu(Ac)2·H2O和配合物对金黄色葡萄球菌、枯草芽孢菌、大肠杆菌有一定的抑制作用,其中配合物对金黄色葡萄球菌和枯草芽孢菌的抑菌效果明显。同时对配合物进行了循环伏安特性研究。循环伏安图显示该配合物有一对准可逆的阴极峰和阳极峰。

The Cu（L-ile）2（H2O） was synthesized from L-Isoleucine and Cupric acetate and structurally characterized by means of single-crystal X-ray diffraction.X-ray data revealed that the titled complex crystallized in the orthorhombic system,space group P212121.The Ligand,Compound and Cu（Ac）2·H2O showed a certain antibacteriostatic property to Staphylococcus aureus,Bacillus subtili and Escherichia codi using an agar diffusion antimicrobial text.The electrochemical properties of the compound were investigated by the cyclic voltammogram.The CV of Cu（L-ile）2（H2O） demonstrated that there were quasi-reversible cathode and anodic peaks.
