草酸根桥联的Cd_3~ⅡFe~Ⅲ异四核配合物的合成、表征和抗菌活性

SYNTHESIS CHARACTERIZATION AND THE ANTIBACTERIAL ACTIVITIES OF THE HETEROQUADRINUCLEAR COMPLEXES THROUGH OXALATO BRIDGE

合成了三种草酸根桥联的新型CdⅡ3 FeⅢ 异四核配合物 [Cd3 Fe(OX) 3 L6](ClO4 ) 3 ,L分别为 1,10_邻菲咯啉 (phen) ;5_硝基_1,10_邻菲咯啉 (NO2 _phen) ;2 ,9_二甲基_1,10_邻菲咯啉 (Me2 _phen) ;OX表示草酸根阴离子 .经元素分析、摩尔电导的测定以及红外光谱的研究 ,已推断这些配合物具有草酸根结构 ,其中Cd(Ⅱ )和Fe(Ⅲ )离子均处于八面体构型 .测试了这些配合物的抗菌活性 ,结果表明 ,这些异四核配合物的抑菌活性优于配体的抑菌活性 .

Three new oxalate_bridged heteroquadrinuclear complexes,[Cd 3Fe(OX) 3L 6](ClO 4) 3,have been synthesized,L denotes 1,10_phenanthroline、5_nitro_1,10_phenanthroline and 2,9_dimethyl_1,10_phenanthroline respectively.Based on the elemental analyses,molar conductance and IR studies,these complexes are proposed to have oxalate_bridged structures,Cd(Ⅱ)and Fe(Ⅲ) are all located in the octahedral environment.The antibacterial activities of these complexes are measured, and the results show that the antibacterial activities of these heteroquadrinuclear complexes are superior to the chelating agent.
