title: (E)-N'-(5-Chloro-2-hydroxy-benzyl-idene)-p-toluene-sulfonohydrazide.
abstract: The title compound, C(14)H(13)ClN(2)O(3)S, features an intra-molecular O-H⋯N hydrogen bond which generates an S(6) ring motif. Inter-molecular N-H⋯O hydrogen bonds and C-H⋯O close contacts link neighbouring mol-ecules forming R(2) (2)(13) ring motifs. In the crystal structure, mol-ecules are further linked by C-H⋯Cl inter-actions, forming one-dimensional extended chains along the c axis. The dihedral angle between the two benzene rings is 86.06 (3)°. The crystal structure is further stabilized by weak inter-molecular π-π inter-actions [inter-planar stacking distance = 3.357 (7) Å].
