Peroxovanadium (V) species of notional formula VO (OO) +, HVO2 (OO) 22–, H2VO2 (OO) 2–, VO (OO) 33–, HVO (OO) 32–, V (OO) 43–, HVO (OO) 22O3–, and VO (NH3) (OO) 2– have been identified in aqueous solution by 51V n. m. r. spectroscopy; species HVO3 (OO) 2–, VO2 (OO) 23–, and V (OH2) (OO) 22O are also indicated. The chemical shifts and pKa values indicate that peroxo-ligands bind to vanadium less covalently than oxo-ligands, provided that at least one oxo-ligand remains co-ordinated.
