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
