摘要： 合成和表征了6种以草酰胺为桥联的异双核配合物Cu(oxen)Ln(phen)2(ClO4)3(oxen代表N,N'-双(2-氨乙基)草酰胺根阴离子;phen为1,10-邻菲咯琳;Ln表示Y、La、Ce、Nd、Gd和Yb).测定了Cu(oxen)Gd(phen)2(ClO4)3·H2O的变温磁化率(4～300K);井用最小二乘法和从自旋Hamiltonian算符导出的磁方程拟合,求得交换积分J=2.3cm-1;表明配合物中Cu(Ⅱ)和Gd(Ⅲ)离子间存在弱的铁磁性超交换作用.测试了配合物的抗菌活性.

Abstract: Six μ-oxamido heterobinuclear complexes,namely Cu(oxen)Ln(phen)2(ClO4)3,(oxen:N,N'-bis(2-aminoethyl)oxamido dianion;phen:1,10-phenanthroline and Ln:Y,La,Ce,Nd,Gd,Yb)have been synthesized and characterized.The variable-temperature mag-netic susceptibility of Cu(oxen)Gd(phen)2(ClO4)3· H2O was measured over 4～300K andthe susceptibility data were least-squares fit to the susceptibility equation derived from thespin HamiItonian operator The exchange integral J was found to be2.3cm-1,indicating that a very weak ferromagnetic spin-exchange interaction operates be-tween Cu(Ⅱ)and Gd(Ⅲ)ions.The antibacterial activity of the complexes were also exam-ined.

Key words: copper-rare earth binuclear complex, synthesis, magnetism, antibacterial activity
