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]
