Abstract: In the title compound, [V(C₂₀H₁₇N₄S)O₂]·C₂H₆OS, the organic ligand coordinates the metal atom in a tridentate manner via its azomethine nitrogen, thiolate sulfur and pyridyl (py) nitrogen atoms, resulting in two five-membered chelate rings. To match the steric requirements of coordination through the N_py-N-S chelating system, the 1-[(2-pyridyl)(phenyl)methylene]-4-(p-tolyl)thiosemicarbazonate ligand adopts a configuration different to that of the parent thiosemicarbazone. The V atom shows a distorted trigonal-bipyramidal coordination geometry.
