Abstract

The complexes formed between D-3-phosphoglyceric acid and H+, Cu(II) and VO(IV) were studied by pH-potentiometric and spectral (UV-Vis, EPR and CD) methods in order to describe the speciation of the metal ions and to determine the most probable binding modes in the complexes formed in these systems. The results show that, in the pH range between 2 and 4, mononuclear 1:1 complexes are formed through bidentate (MAH) or tridentate (MA) coordination of the ligand. At higher pH, when the proton competition for the central alcoholic-OH function decreases, alcoholate-bridged dinuclear species of composition M2A2H-n (n=1-3) become predominant. VO(IV) seems to have a higher tendency than Cu(II) to form such dinuclear complexes.
