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]
