Vanadium(III) acetylacetonate explained

Vanadium(III) acetylacetonate should not be confused with vanadyl acetylacetonate.

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]
