Vanadyl ion

The vanadyl ion is a polyatomic ion (chemical compound with electrical charge) made of vanadium and oxygen, with the chemical formula VO2+.

Because of the small size and high charge of the vanadium atom, it is an unusual example of a stable polyatomic cation containing a transition metal.

It has a characteristic blue colour, as seen in the mineral cavansite. Vanadyl ions occur in seawater.
