In the title compound, C(13)H(11)Cl(2)NO(2)S, the conformation of the N-H bond in the C-SO(2)-NH-C segment is anti to the meta-Cl atom on the aniline ring and syn to the ortho-methyl group on the sulfonyl-benzene ring. Furthermore, the torsion angle of the C-SO(2)-NH-C segment in the mol-ecule is 80.1 (3)°. The two benzene rings are tilted relative to each other by 70.9 (1)°. In the crystal, pairs of inter-molecular N-H⋯O hydrogen bonds link the mol-ecules via inversion-related dimers into infinite column-like chains.
在标题化合物C(13)H(11)Cl(2)NO(2)S中，C-SO(2)-NH-C片段中N-H键的构象与苯胺环上的间位氯原子呈反式，与磺酰苯环上的邻位甲基呈顺式。此外，分子中C-SO(2)-NH-C片段的扭转角为80.1 (3)°。两个苯环彼此倾斜70.9 (1)°。在晶体中，分子间的N-H⋯O氢键对通过与反演相关的二聚体将分子连接成无限的柱状链。
