Pervanadyl is jargon that has two meanings.
- Pervanadyl can refer to aquo complexes containing (VO+2). This pale yellow[1] oxycation of vanadium(V) is the predominant vanadium(V) species in acidic solutions with pH between 0 and 2. Like permanganate, pervanadate features the metal in its highest oxidation state.
- Pervanadyl also can refer to peroxo derivatives of vanadium(V) which are often abbreviated VO(O2)+.[2] Several vanadium(V) peroxides have been characterized.[3]
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]
