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.
