N-(2,3-Dichlorophenyl)-2-nitrobenzenesulfonamide

In the title compound, C12H8Cl2N2O4S, the N-C bond in the C-SO2-NH-C segment has gauche torsions with respect to the S O bonds. Further, the N-H bond is syn to the orthonitro group in the sulfonyl benzene ring and also syn to both the ortho-and meta-Cl atoms in the aniline ring. The molecule is twisted at the S-N bond with a torsion angle of 61.15 (18)degrees. The dihedral angle between the planes of the benzene rings is 68.00 (6)degrees. The amide H atom exhibits an intramolecular bifurcated N-H center dot center dot center dot(O, O) hydrogen bond. In the crystal, pairs of N-H center dot center dot center dot O(S) hydrogen bonds link the molecules into inversion dimers with R-2(2) (8) motifs.
