2,4-Dichloro-N-(2,3-dichlorophenyl)benzenesulfonamide

In the title compound, C12H7Cl4NO2S, the conformation of the N—C bond in the C—SO2—NH—C segment is gauche with respect to the S=O bonds. Further, the N—H bond in the C—SO2—NH—C segment is syn with respect to the ortho-Cl atoms in the aniline and sulfonyl benzene rings. The C—SO2—NH—C torsion angle is −51.98 (18)°. The sulfonyl and aniline benzene rings are tilted by 67.7 (1)° relative to each other. An intramolecular N—H⋯Cl hydrogen bond occurs.
