酸性磷(膦)酸酯与许多金属离子都能形成配位化合物,Sato等曾对二(2-乙基已基)磷酸(DEHPA)在盐酸体系中萃取VO~(2+)的配合物,进行了ESR波谱研究,但未能得到分辨较好的波谱。 本文合成了几种酸性磷(膦)酸酯的VO~(2+)配合物,并在不同溶剂中,室温时进行了ESR波谱研究,讨论了它们可能的结构。
Acid phosphorus (phosphonates) and many metal ions can form a coordination compound, Sato and other once on the di (2-ethylhexyl) phosphate (DEHPA) in the hydrochloric acid system extraction VO ~ (2+) The ESR spectra were studied, but the spectra were not well resolved. In this paper, several VO ~ (2+) complexes of acidic phosphine (phosphonate) were synthesized and studied by ESR spectroscopy in different solvents at room temperature. Their possible structures were discussed.
