Oxido[2-{(E)-[((1E)-{(E)-2-[1-(2-oxido-phen-yl)ethyl-idene]hydrazin-1-yl-idene}(prop-2-en-1-ylsulfan-yl)meth-yl)-imino]-meth-yl}phenolato]vanadium(IV).
The V(IV) atom in the title complex, [V(C(19)H(17)N(3)O(2)S)O], is coordinated by two N and two O atoms of the dianionic tetra-dentate Schiff base ligand and the terminal oxide O atom. The N(2)O(3) donor set defines a square-pyramidal coordination geometry with the oxide O atom in the apical site. Some buckling in the tetra-dentate ligand is indicated by the dihedral angle of 17.92 (19)° between the six-membered chelate rings. Supra-molecular 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 inter-actions. The atoms comprising the -SCH(2)-CH=CH(2) 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.
