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 and the susceptibility data were least-squares fit to the susceptibility equation derived from the spin Hamiltonian operator Ĥ=-2JŜ1·Ŝ2. The exchange integral J was found to be 2.3cm-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.
