N-(2,4-Dichloro-phen-yl)-4-methyl-benzene-sulfonamide.

ABSTRACT: The mol-ecule of the title compound, C(13)H(11)Cl(2)NO(2)S, is bent at the S atom with a C-SO(2)-NH-C torsion angle of -69.07 (16)°. The sulfonyl and aniline rings are rotated relative to each other by 53.0 (1)°. In the crystal, pairs of N-H⋯O(S) hydrogen bonds link the mol-ecules into centrosymmetric dimers.
