摘要： 钒的氨基酸配合物具有重要的生物和医学意义。VO(Ⅱ)-组氨酸配合物及VO(Ⅱ)-π受体二元配合物的ESR研究已有报道。但是VO(Ⅱ)-氨基酸-π受体三元配合物的结构及其ESR研究至今未见报道。本文考察了VOSO4与组氨酸(His)和邻菲啰啉(Phen)及α,α′-联吡啶(bipy)三元体系在不同酸度(pH=1～14)的乙二醇/水(1:1)溶液中低温(173K)ESR波谱,获得了不同pH条件下配合情况的详细信息。

关键词: 组氨酸, π受体, VO(Ⅱ)配合物, ESR波谱

Abstract: The ESR spectra of VO-His-Phen and VO-His-bipy ternary systems in glycol/water(1:1) solution at various acidity have been observed at 173K. It was found that different structural complexes were formed depending on the pH value of the solution. Their possible structures were suggested according to Johnson's rule.

Key words: histidine, π-acceptor ligand, VO(Ⅱ), complex, ESR
