title: N-(2,3-Dimethyl-phen-yl)-2-nitro-benzene-sulfonamide.
abstract: There are two independent mol-ecules in the asymmetric unit of the title compound, C(14)H(14)N(2)O(4)S. 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 mol-ecules are twisted at the S-N bonds with torsion angles of -60.4 (3) and 58.8 (3)° in the two mol-ecules. The dihedral angles between the planes of the sulfonyl and the anilino benzene rings are 53.67 (8) and 56.99 (9)°. The amide H atoms of both mol-ecules are involved in an intra-molecular hydrogen bond, generating an S(7) motif. In the crystal, pairs of N-H⋯O(S) hydrogen bonds link like mol-ecules into inversion dimers.
