Vanadyl(acetylacetonate) is the acetylacetonate anions, acac⁻. Like other charge-neutral acetylacetonates, this complex is soluble in organic solvents.

Synthesis

The complex is prepared from vanadium(IV) or vanadium(V) precursors, the latter being more convenient:^[1]

2 (CH₃CO)₂O + 5 H₂O

Structure and properties

The complex has a square pyramidal structure with a short V=O bond. This d¹ compound is paramagnetic. Its optical spectrum exhibits two transtions. It is a weak Lewis acid, forming methylamine.^[1]

Applications

It is used in hydroperoxide.^[2]
