Not to be confused with the pervanadyl ion, with the formula VO+ 2.
The vanadyl or oxovanadium(IV) cation, VO2+,[1] is a functional group that is common in the coordination chemistry of vanadium. Complexes containing this functional group are characteristically blue and paramagnetic. A triple bond is proposed to exist between the V4+ and O2− centers.[2] The description of the bonding in the vanadyl ion was central to the development of modern ligand-field theory.[3]
VO2+, often in an ionic pairing with sodium (NaH2VO4), is the second most abundant transition metal in seawater, with its concentration only being exceeded by molybdenum.[4] In the ocean the average concentration is 30 nM. Some mineral watersprings also contain the ion in high concentrations. For example, springs near Mount Fuji often contain as much as 54 μg per liter.[4]
