Synthesis and Characterization of Lanthanides with Quinaldic Acid and o-Phenanthroline Ternary Complexes

报道了镧系元素Ln(Ⅲ)(Ln=Sm,Eu,Tb)离子与2-羧基喹啉及1,10-二氮杂菲反应形成三元配合物。考察了其红外光谱、荧光光谱、热谱,测定了X-射线粉末衍射及元素分析数据。确定了该类配合物的组成为:Ln(Qld)_2(phen)_2·H_2O.(Qld代表2-羧基喷啉,phen代表1,10-二氮杂菲)。

Lanthanides (Sm~(3+), Eu~(3+) and Tb(3+) ternary complexes with quinaldic acid (Qld) and o-phenanthroline (phen) are synthesized and characterized by elemen- tary analysis, infrared spectra, fluorescence spectra, thermal analysis and X-ray powderldiffraction. The data of elementary analysis indicate that a general formula is Ln(Qld)_2(phen)_2·H_2O.
