title: 2-Chloro-N-(3-chloro-benzo-yl)benzene-sulfonamide.
abstract: The asymmetric unit of the title compound, C(13)H(9)Cl(2)NO(3)S, contains two independent mol-ecules. The conformation of the C=O bond is anti to the meta-Cl group in the chloro-benzoyl group of one of the mol-ecules and syn in the other. The dihedral angles between the sulfonyl and benzoyl benzene rings are 77.8 (1) and 83.5 (1)°. In the crystal structure, two pairs of independent mol-ecules are linked into a tetra-mer by N-H⋯O hydrogen bonds.
