4-Chloro-N-(3-chloro-phen-yl)-2-methyl-benzene-sulfonamide.

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.
