| 中文摘要: |
| 合成了分子式为La (Phen)2(Gly)(NO3)3·3H2O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)(H2O)](NO3)2·2H2O. |
| 英文摘要: |
| The solid complexes La（Phen）2（Gly）（NO3）3·3H2O was synthesized. The structure and spectroscopic properties of the complexes was studied by element analysis, molar conductivity, FT-IR spectroscopy, UV spectroscopy and TG-DTA measurements. These gave the results that Two nitrogen atoms of 1,10-phenanthroline, oxygen donor sites of glycine and H2O, nitrogen of NO3- were coordinated to the trivalent lanthanide La, so the coordination number of La was 8. The composition of the complex obtained was confirmed as [La（Phen）2（Gly）（NO3）（H2O）]（NO3）2·2H2O. |
