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-H⋯Cl inter-action is also present.
在标题化合物C(13)H(11)Cl(2)NO(2)S的晶体结构中，C-SO(2)-NH-C片段中N-C键的构象相对于S=O键为反式和gauche式。C-S(O(2))-N(H)-C扭转角为74.8 (4)°，表明分子在S原子处弯曲。在晶体结构中，通过N-H⋯O氢键对连接的反演二聚体出现。还存在分子内N-H⋯Cl相互作用。
