In the title compound, C(12)H(8)Cl(3)NO(2)S, the conformation of the N-H bond in the C-SO(2)-NH-C segment is anti to the meta-Cl in the aniline ring. The mol-ecule is twisted at the S atom, the C-SO(2)-NH-C torsion angle being 62.3 (2)°. The dihedral angle between the two benzene rings is 69.3 (1)°. The crystal structure features inversion dimers linked by pairs of N-H⋯O hydrogen bonds.
在标题化合物C(12)H(8)Cl(3)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。分子在S原子处发生扭曲，C-SO(2)-NH-C扭转角为62.3 (2)°。两个苯环之间的二面角为69.3 (1)°。晶体结构的特征是通过N-H⋯O氢键对连接形成的反演二聚体。
