N-(2,3-Dimethylphenyl)-2-nitrobenzene-sulfonamide

There are two independent molecules in the asymmetric unit of the title compound, C14H14N2O4S. The N-H bonds are syn to the ortho-nitro groups in the sulfonyl benzene rings and anti to the methyl groups in the aniline benzene rings. The molecules are twisted at the S-N bonds with torsion angles of -60.4 (3) and 58.8 (3)degrees in the two molecules. The dihedral angles between the planes of the sulfonyl and the anilino benzene rings are 53.67 ( 8) and 56.99 (9)degrees. The amide H atoms of both molecules are involved in an intramolecular hydrogen bond, generating an S(7) motif. In the crystal, pairs of N-H center dot center dot center dot O(S) hydrogen bonds link like molecules into inversion dimers.
