The VIV atom in the title complex, [V(C19H17N3O2S)O], is coordinated by two N and two O atoms of the dianionic tetradentate Schiff base ligand and the terminal oxide O atom. The N2O3 donor set defines a square-pyramidal coordination geometry with the oxide O atom in the apical site. Some buckling in the tetradentate ligand is indicated by the dihedral angle of 17.92 (19)° between the six-membered chelate rings. Supramolecular chains are formed along the b axis via C—H...O contacts in the crystal. The chains are connected into a layer in the ab plane via C—H...π interactions. The atoms comprising the –SCH2—CH=CH2 and methyl substituents were found to be disordered in a 0.916 (2):0.088 (2) ratio. The crystal studied was found to be twinned by nonmerohedry with a 28.1 (4)% minor twin component.
