Cyano­methyl 4-(4-methyl­benzene­sulfonamido)­benzoate

The title mol­ecule, C(16)H(14)N(2)O(4)S, adopts an L-shaped conformation, with the central C—S—N—C torsion angle being −69.1 (3)°. The two benzene rings form a dihedral angle of 89.94 (15)°. The mol­ecular conformation may be influenced by a weak intra­molecular C—H⋯O hydrogen bond which generates an S(6) ring motif. In the crystal, mol­ecules are linked by N—H⋯O and weak C—H⋯O hydrogen bonds, forming chains propagating along the b axis. Weak C—H⋯N hydrogen bonds connect the chains into a two-dimensional network parallel to (011). The crystal studied was an inversion twin, the ratio of components being 0.7 (1):0.3 (1).
