Synthesis, Characterization and Antibacterial Activity of Cu_2~ⅡFe~Ⅲ, Ni_2~ⅡFe~Ⅲ, Co_2~ⅡFe~Ⅲ Heterotrinuclear Complexes Through Oxalate Bridge

合成了 7种草酸根桥联的 Cu 2 Fe 、Ni 2 Fe 、Co 2 Fe 异三核配合物 [M2 Fe(C2 O4) 3Lx](Cl O4) ,(M=Cu,L=bpy,Me2 phen,NO2 phen,x=2 ;M=Ni,Co,L=bpy,Me2 phen,x=4 ) .经元素分析、摩尔电导和磁性的测定以及红外光谱和电子光谱等方法对这些配合物进行了表征 ,确定了配合物的组成和结构 .

Seven novel oxalate bridged heterotrinuclear complexes with general formula [M 2Fe (C 2O 4) 3L x ](ClO 4)(M=Cu,L=bpy,Me 2phen,NO 2phen, x =2; M=Ni,Co,L=bpy,Me 2phen, x =4) have been synthesized and characterized by elemental analysis, IR, electronic spectra, molar conductance and magnetic moments (at room temperature) measurements. The complexes are suggested to have oxalate bridged structures. The preliminary biological tests indicated that the antibacterial activities of the heterotrinuclear complexes are superior to the ligand.
