| 摘 要： | 合成了除Pm以外的16个稀土与二(2,4,4-三甲基戊基)膦酸(HBTMPP)的固体配合物,其组成为RE(BTMPP)_3,对配合物的性质进行了表征,热分析表明,在氩气中,热分解是一步完成的,在空气中,热分解分二步完成,前者的热分解产物是RE_4 (P_2O_7)_3,后者的产物为RE_2P_4O_(13)测定了配合物的振动光谱,对其主要吸收谱带进行了归属,配合物中RE-O键具有较高的离子特性

| Abstract: | The solid complexes of 16 rare earth elements with bis (2,4,4-trimethylpentyl)phosphinic acid (HBTMPP) were synthesized and their composition was identified to beRE(BTMPP)_3. The thermal analyses of the complexes were studied in Ar or air. Thethermo-decomposition residues of the complexes were verified by element analysis, infraredspectra and X-ray diffraction to be RE_4(P_2O_7)_3 in Ar or RE_2P_4O_(13) in air. The infrared andRaman spectra were measured for RE(BTMPP)_3 and principal absorption bands were as-signed. The results showed that the RE-O bands of RE(BTMPP)_3 are principally ionic. |
