In the crystal structure of the title compound, C(13)H(11)Cl(2)NO(2)S, the conformations of the N-C bond in the C-SO(2)-NH-C segment are trans and gauche with respect to the S=O bonds. The C-S(O(2))-N(H)-C torsion angle is 74.8 (4)°, indicating that the mol-ecule is bent at the S atom. In the crystal structure, inversion dimers linked by pairs of N-H⋯O hydrogen bonds occur. An intramolecular N-...
