摘　　要：Four new heterotrinuclear complexes have been synthesized and characterized, namely [(CoL 2) 2Cu(pbaOH)](ClO 4) 2, where pbaOH denotes 2 hydroxy 1,3 propylenebis(oxamato) and L stands for 1,10 phenanthroline(phen), 5 nitro 1,10 phenanthroline(NO 2 phen), 2,2 bipyridyl(bpy) and 4,4 dimethyl 2,2 bipyridyl(Me 2bpy). The temperature dependence of the magnetic susceptibility of [(Cophen 2) 2Cu(pbaOH)](ClO 4) 2·H 2O has been studied in the range of 4—300 K, the plot of χ M T vs. T exhibits a minimum at about 120 K, but abnormal magnetic behavior below 78 K.Four new heterotrinuclear complexes have been synthesized and characterized, namely [(CoL_(2))_(2)Cu(pbaOH)](ClO_(4)) _(2), where pbaOH denotes 2-hydroxy-1,3- propylenebis(oxamato) and L stands for 1,10-phenanthroline(phen), 5-nitro- 1,10-phenanthroline(NO_(2)-phen), 2,2-bipyridyl(bpy) and 4,4-dimethyl-2,2-bipyridyl(Me_(2)bpy).
