Abstract: The crystal structure of the title compound, [VO(C₅H₇O₂)₂(C₅H₅N)], has been reported previously [Meicheng, Lifeng & Youqi (1984). Kexue Tongbao, 29, 759-764], with an R value of 0.13. The current redetermination shows a significant improvement in the precision of the geometric parameters. The V atom binds five O atoms and one N atom from the pyridine ligand in a distorted octahedral configuration; the acetylacetonate anions act as bidentate ligands. A crystallographic twofold axis passes through the V, vanadyl O, and pyridine N and para-C atoms.
