摘要
Four new μ-oxamido heterobinuclear complexes of CuII-LnIII (Ln: Y,Pr, Ho. Gd)were synthesized and characterized. The magnetic susceptibility measurements(4~300K)of the CuII-GdIII complex indicate a weak ferromagnetic interaction between thetwo metal ions, with the exchange integral JCu-Gd=2.03 cm-1.
