| 摘 要： | 本文通过组成和物相分析证明按Roy和Okarfor的方法所合成的不是RE(PMBP)3而是RE(PMBP)3·HPMBP络合物。我们提出一种合成RE(PMBP)3络合物的新方法,井用此法合成了45种稀土与HPMBP的固体络合物,对它们进行了组成分析,红外光谱和核磁共振谱等研究,其中有30种为新化合物。

| Abstract: | Since the coordination number of lanthanides is usually 8 or more, it is quite difficult to prepare the hexa-coordinated rare earth complexes of pyrazolone of composition REA3·Recently Roy and Okafor reported the synthesis of 8 rare earth complexes of the title ligand and it was said which had the composition of REA3·We have repeated their experiments many times, but the products obtained and very carefully characterized always remained REA3·HA. In the present investigation, we have synthe-sized 15 REA3·CeA4 and 15 REA3·2H3O complexes by a new procedure, and also 14 REA3·HA complexes. The composition of these 45 complexes was carefully characterized by elemental analysis, Fourier transform infrared spectra in the far and middle infrared range and NMR studies. Among these 45 compounds, 30 have not been reported previously. |
