摘要: Four new heterotrinuclear complexes have been synthesized and characterized, namely [(CoL2)2Cu(pbaOH)](ClO4)2, where pbaOH denotes 2-hydroxy-1,3-propylenebis(oxamato) and L stands for 1,10-phenanthroline(phen), 5-nitro 1,10-phenanthroline(NO2 phen), 2,2'-bipyridyl(bpy) and 4,4'-dimethyl-2,2'-bipyridyl(Me 2bpy). The temperature dependence of the magnetic susceptibility of [(Cophen2)2Cu(pbaOH)](ClO4)2·H2O has been studied in the range of 4—300 K, the plot of χM Tvs. T exhibits a minimum at about 120 K, but abnormal magnetic behavior below 78 K.
