Synthesis and Characterization of the Solid Complexes of Samarium and Gadolinium Ions with Tetraisopropylmethylenediphosphonate and Phenanthroline

分别以氯化钐和氯化钆与亚甲基双膦酸四异丙基酯(L)和邻菲啰啉(phen)合成了四种固体稀土配合物SmL2Cl3(H2O)5(I)、Gd2L3Cl6(H2O)6(Ⅱ)、Sm2L3(phen)2Cl6(H2O)10(Ⅲ)和Gd2L3(phen)2Cl6(H2O)4(Ⅳ).用元素分析、TG-DTA分析、红外光谱、1H与31P核磁共振谱和荧光光谱对配合物的组成、结构和光谱性质进行了表征.

Four solid rare earth complexes, SmL2 Cl3 （ H2O）5 （ Ⅰ ）, Gd2L3Cl6 （ H2O）6 （Ⅱ ）、 Sm2L3 （ phen）2Cl6 （ H2O）10 （ Ⅲ）和 Gd2L3 （phen）2Cl6 （H2O）4 （Ⅳ）,have been synthesized by reactions of samarium chloride and gadolinium chloride with tetraisopropylmethylenediphosphonate and phenanthroline respectively. The structure, spectra property and composition of the complexes have been characterized by element analysis, TG-DTA analysis, infrared spectra, 1^H NMR, 31^P NMR and luminescence spectra.
