Vanadium(III) acetylacetonate is the coordination compound with the formula V(C₅H₇O₂)₃, sometimes designated as V(acac)₃. It is an orange-brown solid that is soluble in organic solvents.

Structure and synthesis

The complex has idealized D₃ symmetry.^[1] Like other V(III) compounds, it has a triplet ground state.

The compound is prepared by reduction of ammonium vanadate in the presence of acetylacetone.^[2]

Applications and research

V(acac)₃ is a common precatalyst for the production of EPDM polymers.^[3]

It has also been shown to be a precursor to vanadium pentoxide nanostructures.^[4]
