title: N-(2,5-Dichloro-phen-yl)benzene-sulfonamide.
abstract: In the title compound, C(12)H(9)Cl(2)NO(2)S, the conformation of the N-H bond is syn to the 2-chloro group and anti to the 3-chloro group of the aniline benzene ring. The mol-ecule is bent at the S atom with a C-SO(2)-NH-C torsion angle of 66.4 (2)°. The two rings form a dihedral angle of 73.3 (1)° and an intra-molecular N-H⋯Cl hydrogen bond occurs. The crystal structure features chains linked by N-H⋯O hydrogen bonds.
