Three new heterotrinuclear complexes have been synthesized and characterized, namely {[Gd(L)2]2 [Cu (pbaOH)]} (ClO4)4, where pbaOH denotes 2-hydroxy-1, 3-propylenebis(oxamato), L stands for 1, 10-phenanthroline (phen), 5-nitro-1, 10-phenan-throline (NO2-phen) or 2, 2'-bipyridyl (bpy).The temperature dependence of the magnetic susceptibility of {[Gd(phen)2 (ClO4)2]2 [Cu (pbaOH)]} (ClO4)2 has been studied in the 4-300K range, giving the exchange integral J=6.69 cm-1.This indicates a weak ferromagnetic interaction between the copper(Ⅱ) and gadolinium (Ⅲ) ions.
