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]
