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

ABSTRACT: 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 syn to the ortho-Cl in the aniline ring. The dihedral angle between the two benzene rings is 74.3 (1)°. An intra-molecular N-H⋯Cl hydrogen bond occurs. In the crystal, pairs of N-H⋯O hydrogen bonds link the mol-ecules into dimers.
