Vanadyl ion

The vanadyl ion is an oxovanadium cation, either VO2+ (called oxovanadium(IV)) or VO3+ (called oxovanadium(V)). They are functional groups that are common in the coordination chemistry of vanadium.

Natural occurrence
Minerals Cavansite and pentagonite are vanadyl-containing minerals. Water 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. In the ocean the average concentration is 30 nM. Some mineral water springs also contain the ion in high concentrations. For example, springs near Mount Fuji often contain as much as 54 μg per liter. ==Vanadyl-containing compounds ==
