摘　　要：合成了苯甲酸铽和苯甲酸镧配合物 ,以 4 ,4′-联吡啶将两配合物连结起来 ,形成了苯甲酸 4 ,4′-联吡啶双配体异核稀土配合物。对合成的配合物进行了元素分析 ,测定了其摩尔电导、红外光谱及荧光光谱。结果表明 ,配合物的组成为Tb La L6 L′· 2 H2 O( L=苯甲酸根 ,L′=4 ,4′-联吡啶 ) ;配合物在 2 95 nm紫外光激发下 ,发出较强的特征荧光 。The complex of terbium and lanthanum with benzoate and 4,4′ dipyridyl was synthesized. Elemental analysis showed that the composition is TbLaL 6L′·2H 2O(L is benzoate and L′ is 4,4′ dipyridyl). Its infrared spectra,molar conductance and fluorescence spectra were measured. The results indicated that the chemical bonds were formed between both ligands and the rare earth ions. The fluorescence intensity of the complex excited by 295 nm light is stronger than that of the complex of terbium benzoate. The complex TbLaL 6L′ is a good luminescent complex.
