合成和表征了三种新的异三核配合物, {[Gd(L)2]2[Cu(pba)]}(ClO4)4,其中pba为1,3-亚丙基双(草胺酸根)和L表示1,10-菲咯啉(phen),5-硝基-1,10-菲咯啉(NO2-phen)或2,2'-联吡啶(bpy)。基于{[Gd(phen)2(ClO4)]2[Cu(pba)]}(ClO4)2.2H2O的变温磁化率测量(4.1~300K),求出交换积分J=3.576cm^-^1。表明在铜(Ⅱ)和钆(Ⅲ)离子间存在铁磁性偶合。

Three novel heterotrinuclear complexes have been synthesized and characterized, namely {[Gd(L)2]2[Cu(pba)]}(ClO4)4, where pba denotes 1,3-propylenebis (oxamato), L stands for 1,10-phenanthroline (phen), 5-nitro-1,10-phenanthroline (NO2-phen) or 2,2'-bipyridyl (bpy). The temperature dependence of the magnetic susceptibility of {[Gd(phen)2-(ClO4)]2[Cu(pba)]}(ClO4)2.2H2O has been studied in the 4~300K range, giving the exchange intergral J=3.56cm^-^1. This indicates a weak ferromagnetic interaction between the copper (Ⅱ) and gadolinum (Ⅲ) ions.

Key words: COPPER COMPLEX, POLYNUCLEAR COMPLEX, BIPYRIDINE, PHENANTHROLINE, GADOLINIUM COMPLEX, FERROMAGNETISM, INTERACTIONS
