Abstract: The ESR spectra of VO-Glu and VO-Glu-phen systems in glycol/water (1∶1) mixture with various acidity have been recorded at 173K.It is found that the constitution ofthe complexes is in dependence on the pH values of the solution. Their possible structureswere suggested according to Johnson′s rule and IR values. By using electronic spectral datathe crystal field parameters were calculated.
