(E)-N′-(5-Chloro-2-hydroxy­benzyl­idene)-p-toluene­sulfonohydrazide

The title compound, C(14)H(13)ClN(2)O(3)S, features an intra­molecular O—H⋯N hydrogen bond which generates an S(6) ring motif. Inter­molecular N—H⋯O hydrogen bonds and C—H⋯O close contacts link neighbouring mol­ecules forming R (2) (2)(13) ring motifs. In the crystal structure, mol­ecules are further linked by C—H⋯Cl inter­actions, 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 inter­molecular π–π inter­actions [inter­planar stacking distance = 3.357 (7) Å].
