Bis(acetylacetonato)oxovanadium(IV) (VO(acac)2) was synthesized from vanadium(V)
oxide (V2O5) via two synthetic routes using different acids. The obtained products were
crystallized from several solvents, and reactions with nitrogen-donor ligands were carried
out. The resulting products were characterized by powder X-ray diffraction (PXRD).
VO(acac)2 was identified as the main crystalline phase in the products obtained by both
synthetic routes. Upon crystallization from most of the tested solvents, the main
crystalline phase was retained, whereas crystallization from DMF resulted in diffraction
patterns suggesting the possible formation of a new crystalline phase. In the reactions
with nitrogen-donor ligands, products with a lower degree of crystallinity compared with
the starting compounds were obtained; therefore, the formation of new coordination
compounds could not be reliably confirmed based on the PXRD data.
