SYNTHDSIS OF Cd~ⅡFe~Ⅲ HETEROTETRANUCLEAR COMPLEXES THROUGH OXALATE BRIDGES

合成和表征了二种新的草酸根桥联的异四核配合物 [Cd3Fe(C2 O4 ) 3(bpy) 6 ] (ClO4 ) 3(1)和 [Cd3Fe(C2 O4 ) 3(Me2 bpy) 6 ](ClO4 ) 3(2 ) ,其中bpy表示 2 ,2 -联吡啶 :Me2 bpy表示 4,4-二甲基 -2 ,2 -联吡啶 .经元素分析 ,摩尔电导和红外光谱等手段推定配合物具有草酸根桥联结构 .生物活性试验表明 。

Two new oxalate-bridged heterotetranuclear complexes have been synthesized and characterized, namely [Cd 3Fe(C 2O 4) 3L 6](ClO 4) 3,L denotes 2,2 -dipyridyl and 4,4-dimethyl-2,2-dipyridyl, respectively. Based on elemental analysis,IR and molar conductivity measurements,the complexes are proposed to have oxalate-bridged structures.The experimental results show that antibacterial activities of the heterotetranuclear complexes are superior to the ligand.
