N-(3-Chlorobenzoyl)-2-nitrobenzenesulfonamide

Abstract

In the title compound, C13H9ClN2O5S, the N—C bond in the C—SO2—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 molecule 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 –SO2—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.
