Abstract: The title molecule, C9H11N3OS, exhibits a trans conformation with respect to the phenyl ring and the thiosemicarbazone moiety. The dihedral angle between the thiosemicarbazone moiety and the phenyl ring is 4.68 (5)°. In the solid state, inversion-related molecules exist as centrosymmetric N-HS hydrogen-bonded dimers. Symmetry-related dimers are interlinked by N-HS and N-HO intermolecular hydrogen bonds, forming two-dimensional molecular networks parallel to the ab plane.
