Vanadyl acetate is the coordination polymer with the empirical formula VO(CH3COO)2, which can be simplified to VO(OAc)2 and giving rise to a systematic name of vanadium(IV) oxide diacetate. It is a tan solid, insoluble in most solvents.
Production and structure Vanadyl acetate is produced by treating vanadium pentoxide with acetic anhydride. The acetic anhydride serves as the reducing agent converting the vanadium(V) to vanadium(IV); the oxidized byproduct of the reaction has not been identified. V2O5 + 3 (CH3CO)2O → 2 VO(CH3COO)2 + 2 CO2 + ...
This compound has a linear polymeric structure consisting of repeating VO6 octahedra.
It forms adducts with pyridine, urea, and thiourea. It also has been reported to catalyzes the acetylation of alcohols.
