New heterobinuclear complexes,[ Cu( phen)(C2O4) Co(dpp)](ClO4)2(1)and [Cu(dien)(C2O4)Co(dpp)](ClO4)2· 2H2O(2), which contain phosphine ligand, were synthesized,where phen, dpp and dien denote phenanthroline, bis( 2-diphenylphosphinoethyl) phenylphosphine and diethylenetrimine respectively.The complexes were characterized with variable temperature magnetic susceptibility.The exchange integral,J, was found to be-11. 04 cm(-1)(1)and-18. 34 cm(-1)(2), indicating that there exists a weaker antiferro-magnetic spin exchange interaction among the metal ions.
