In the title complex, [V(C15H12N2O4)(C2H5O)O], the VV ion is coordinated by an oxide O atom, an ethanolate anion and two O atoms and one N atom from the tridentate benzohydrazidate dianion in a distorted square-pyramidal geometry; the V atom is displaced by 0.4748 (8) Å from the basal plane towards the axial oxide O atom. An intramolecular O—H⋯N hydrogen bond occurs in the benzohydrazidate ligand. Weak intermolecular C—H⋯O hydrogen bonding is present in the crystal.
