摘要: 合成了新型水杨酰胺型三足配体2,2′,2″-三2-(N-羟甲基甲酰基)苯氧基三乙胺(L)及其稀土苦味酸盐配合物,并用元素分析、核磁、摩尔电导率测定、热重-差热、红外等多种手段对其进行表征。结果表明,配体与稀土苦味酸盐均形成1∶1型的配合物。配合物的组成通式为:RE(Pic3)3L(RE=La,Pr,Eu,Ho),同时研究了配合物的热分解性质。Abstract: A new aryl amide type ligand 2,2′,2″-nitrilotris(2-N-hydroxymethylformyl)phenoxy(trie-)thylamine(L) and a series of lanthanide picrate complexes are synthesized and characterized on the basis of elemental analyses,NMR,electrical conductivity,TG-DTA and IR spectral studies.The results show that all of these complexes have the composition of RE(Pic_3)_3L(RE=La,Pr,Eu,Ho).The thermal properties of these complexes are also discussed.
