Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

Pervanadyl is jargon that has two meanings.

The former are formed by protonation of vanadium(V) oxide in such solutions: [4] [5]

V2O5 + 2 H+ → 2 VO+2 + H2O ( K  = 3.42×10−2)

The ion can form a complex with a single aminopolycarboxylate ligand, [6] or with tridentate Schiff base ligands. [7]

The VO+2/VO2+ redox couple is used at the cathode of the vanadium redox battery. [8] The standard reduction potential of this couple is +1.00 V. [9]
