Abstract
In the title compound, C12H8Cl3NO2S, the conformation of the N—H bond in the C—SO2—NH—C segment is anti to the meta-Cl in the aniline ring. The molecule is twisted at the S atom, the C—SO2—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.
