A pair of new oxidovanadium(V) complexes, [VOLL<sup>1</sup>] (1) and [VOLL<sup>2</sup>] (2), where L is the dianionic form of the hydrazone ligand <i>N′</i>-(2-hydroxy-3-methoxybenzylidene)-3-methylbenzohydrazide (H<sub>2</sub>L), L<sup>1</sup> and L<sup>2</sup> are the deprotonated form of 3-hydroxy-2-methyl-4<i>H</i>-pyran-4-one (HL<sup>1</sup>) and 3-hydroxy-2-ethyl-4<i>H</i>-pyran-4-one (HL<sup>2</sup>), respectively, have been prepared and characterized by elemental analyses, IR, UV-Vis, <sup>1</sup>H NMR and single crystal X-ray determination. The V atoms in the complexes are in octahedral coordination, with the hydrazone ligand coordinates to the metal atoms through the phenolate O, imino N, and enolate O atoms, and with the pyrone ligands through the carbonyl and hydroxyl O atoms. The effect of the compounds on the antimicrobial activity against <i>Staphylococcus aureus</i>, <i>Escherichia coli</i>, and <i>Candida albicans</i> was studied.
