Abstract: ESR spectra of VO2+-Glu-phen and VO2+-Glu-bipy ternary systems in glycol-water (1:1) solution at various acidity have been observed at low temperature (173K).It has been found that in different pH ranges the complexes with different structures were formed.According to Johnsons rule and IR data,their possible structures are suggested.Using electronic spectral data,the crystal field parameters were calculated.

Key words: VO2+-complexes, Glutamic acid, π-Acceptor ligands, ESR spectra
