合成了分子式为La (Phen) 2 (Gly) (NO3 ) 3 ·3H2 O的固体配合物 ,对所合成的配合物进行了元素分析、摩尔电导、IR、UV、TG -DTA等的分析测试 ,初步研究了配合物的组成、结构及性质。结果表明 :所得三元固体配合物中 ,邻菲罗啉的两个氮原子参与配位 ,甘氨酸的羧基离子以桥式双齿配位于稀土离子 ,同时含有一个单齿配位的硝酸根离子和一个配位水 ,故La的配位数为 8,配合物的分子结构可写成 :[La(Phen) 2 (Gly) (NO3 ) (H2 O) ](NO3 ) 2 ·2H2 O。
Solid complexes of La (Phen) 2 (Gly) (NO3) 3 · 3H2O with the molecular formula of La (Phen) 2 (Gly) 3 · 3H2O have been synthesized and analyzed by elemental analysis, molar conductance, IR, UV, TG- Preliminary study of the composition, structure and properties of the complex. The results show that the two nitrogen atoms of phenanthroline are involved in the coordination of the resulting ternary complex, and the carboxylate of glycine bridges the bidentate complex with rare earth ions and contains a monodentate nitrate ion and A coordination water, so the coordination number of La is 8, the molecular structure of the complex can be written as: [La (Phen) 2 (Gly) (NO3) (H2 O)] (NO3) 2 · 2H2O.
