title: 2-Nitro-N-phenyl-benzene-sulfonamide.
abstract: In the title compound, C(12)H(10)N(2)O(4)S, the conformation of the N-H bond in the -SO(2)-NH- fragment is syn to the ortho-nitro group in the sulfonyl-benzene ring. The mol-ecule is twisted at the S-N bond, the C-N-S-C torsion angle being -72.83 (15)°. The dihedral angle between the benzene rings is 59.55 (7)°. The amide H atom and the nitro group O atom form an intra-molecular hydrogen bond, generating an S(7) motif. In the crystal, C-H⋯O hydrogen-bond inter-actions link the mol-ecules into S(2) (2)(10) networks.
