二环己酮草酰二腙桥联的双核镉(Ⅱ)配合物的合成表征及杀菌活性

SYNTHESIS CHARACTERIZATION AND ANTIBACTERIAL ACTIVITIES OF BINUCLEAR CADMIUM(Ⅱ)COMPLEXES BRIDGED BY BISCYCLOHEXANONE OXALYLDIHYDRAZONE

目的 合成新的配合物 ,研究其结构与性质间的关系。方法 以BCO为桥配体 (BCO代表二环己酮草酰二腙 ) ,分别端接Mephen(Mephen代表 5-甲基 - 1,10 -邻菲咯啉 )和Me2 phen(Me2 phen代表 2 ,9-二甲基— 1,10— 1邻菲咯啉 )合成两种配合物 ;经元素分析 ,摩尔电导及红外光谱手段进行表征 ,测试其杀菌活性。结果 推定了配合物的结构 ,其杀菌活性优于BCO。结论 配合物在空气中稳定 ,有较强的杀菌性 ,有进一步研究的价值。

Objective To synthesize new complexes,and study the relations between their structures and natures.Methods Two novel binuclear cadmium(Ⅱ)complexes bridged by biscyclohexanone oxalyldihydrazone have been synthesized,namely 〔Cd 2(BCO)(Mephen) 4〕(ClO 4) 4(1)and 〔Cd 2(BCO)(Me 2phen) 4〕(ClO 4) 4.BCO=biscyclohexanone oxalyldihydrazone;Mephen=5-methyl-1,10-phenanthroline;Me 2phen=2,9-dimethyl-1,10-phenanthroline.Using elemental analyses,molar conductance and IR,measures to test their antibacterial activities.Results Structures of two complexes have been proposed,and their antibacterial activities are superior to BCO.Conclusion Two complexes are stable in the air and their antibacterial activities are strong.They are worth further studies.
