N-[4-(4-Chloro­benzene­sulfonamido)­phenyl­sulfon­yl]acetamide

In the title compound, C₁₄H₁₃ClN₂O₅S₂, the dihedral angles between the central benzene ring and the pendant chloro­benzene ring and the N-acetyl group are 82.35 (5) and 79.71 (6)°, respectively, and the overall conformation of the mol­ecule approximates to a U shape. Both the C—S—N—C conformations are gauche, but with opposite senses [torsion angles = −59.29 (15) and 63.68 (16)°]. An intra­molecular C—H...O inter­action generates an S(6) ring. In the crystal, inversion dimers linked by pairs of N—H...O hydrogen bonds generate R₂²(20) loops. A second N—H...O hydrogen bond links the dimers into (101) layers.
