Abstract: Four novel trinucleat copper(Ⅱ) complexes were synthesized,namely{[Cu(pba)] [Cu(L)]₂}(ClO₄)₂,where pba denotes 1,3-propylenebis(oxamato) and Lis 2,2'-bipyridyl(bpy),4,4'-dimthyl-2,2'-bipyridyl(Me₂bpy),1,10-phenanthroline(phen) or 5-nitro-1,10-phenanthroline(NO₂-phen).Based on IR,elemantry analyses,conductivity measurements and electronic spectra,these complexes were proposed to have oxamido-bridged structures and to consist of three copper(Ⅱ) ions in which each copper(Ⅱ) ion has a square planar envionment.The temperature dependence of the magnetic susceptibility of[Cu(pba)][Cu (NO₂-phen)]₂(ClO₄)₂ has been studied in the range from 4.1 to 300 K,giving the exchange interval J=-124 cm^-1.The result reveals the operation of a strong antiferromagnetic spinexchange interaction between the adjacent copper ions.

Key words: Oxamato bridge, Cu(Ⅱ)-Cu(Ⅱ)-Cu(Ⅱ), Antiferromagnetic interaction
