The ESR spectra of oxovanadium complexes with a,a'-bipyridine, 3,4,7,8-tetramethyl-1,10-phenanthroline and 1,10-phenanthroline in glycol-water (1:1) solns. at various acidity(pH = 1-14) were observed at 77 K. When the pH is < 1.0, A = 118 ?10-4 T is attributed to the complex [VO(H2O)5]2+; when pH > 11, A = 90 ?10-4T is attributed to the bidentate chelate of glycol [VO(OCH2CH2O)2]2-.
