新型草酸根桥联的锌(Ⅱ)-铁(Ⅲ)异四核配合物的合成、表征及杀菌活性

Synthesis,Characterization and Antibacterial Activities of Zinc(Ⅱ)-Iron(Ⅲ) Heterotetranuclear Complexes Through Oxalate Bridges

合成了两种草酸根桥联的异四核配合物 [Zn3 Fe(C2 O4 ) 3 (Mephen) 6](ClO4 ) 3 (1)和 [Zn3 Fe(C2 O4 ) 3(NO2 phen](ClO4 ) 3 (2 ) ,其中Mephen代表 5 甲基 1,10 邻菲咯啉 ;NO2 phen代表 5 硝基 1,10 邻菲咯啉。通过元素分析、摩尔电导和红外光谱等方法对配合物进行了表征 ,推定了配合物具有草酸根桥联结构。

Two new oxalate-bridged heterotetranuclear complexes have been synthesized,namely [Zn 3Fe(C 2O 4) 3(Mephen) 6](ClO 4) 3,Ldenotes 5-methyl-1,10-phenanthroline,respectively.Based on elemental analysis,IR and molar conductivity measurements,two complexes are proposed to have oxalate-bridged strustures.The experimental results show that antibacterial activities of the heterotetranuclear complexes are superior to the ligand.
