Vanadyl acetate is an inorganic chemical compound with the formula VO(CH₃COO)₂, which can be simplified to VO(OAc)₂. It is a tan-colored solid, insoluble in water, that is used to produce other vanadyl acetate complexes such as with pyridine, urea, and thiourea. It also has been studied as a catalyst in the acetylation of alcohols.^[4]

Production and structure

Vanadyl acetate is produced by refluxing acetic anhydride with vanadium pentoxide at 140 °C:^[2]

V₂O₅ + 3 (CH₃CO)₂O → 2 VO(CH₃COO)₂ + 2 CO₂ + C₂H₆

This compound has a polymeric structure consisting of repeating VO₆ octahedra.^[1]
