title: N-(3-Chloro-benzo-yl)-2-nitro-benzene-sulfonamide.
abstract: In the title compound, C(13)H(9)ClN(2)O(5)S, the N-C bond in the C-SO(2)-NH-C segment has a gauche torsion with respect to the S=O bonds. The conformation between the N-H bond and the ortho-nitro group in the sulfonyl benzene ring is syn, and that between the C=O and the meta-Cl atom in the benzoyl ring is anti. The mol-ecule is twisted at the S-N bond, with a torsion angle of 65.41 (38)°. The dihedral angle between the sulfonyl benzene ring and the -SO(2)-NH-C-O segment is 75.0 (1)°, and that between the sulfonyl and the benzoyl benzene ring is 89.1 (1)°. The crystal structure features inversion-related dimers linked by pairs of N-H⋯O(S) hydrogen bonds.
