N-(2,3-Dihydro-1,3-thiazol-2-ylidene)-4-[(2-hydroxybenzylidene)amino]benzenesulfonamide

Abstract

The title compound, C16H13N3O3S2, was prepared by reaction of salicylaldehyde and sulfathia­zole in methanol. The dihedral angle between the central benzene ring and the thia­zole ring is 85.2 (2)° and that between the two benzene rings is 17.9 (2)°. An intra­molecular O—H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol­ecules are held together by inter­molecular N—H⋯N and C—H⋯O hydrogen bonds, forming a two-dimensional network parallel to the bc plane.
