2-Nitro-N-phenylbenzenesulfonamide

In the title compound, C12H10N2O4S, the conformation of the N—H bond in the –SO2—NH– fragment is syn to the ortho-nitro group in the sulfonylbenzene ring. The molecule 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 intramolecular hydrogen bond, generating an S(7) motif. In the crystal, C—H...O hydrogen-bond interactions link the molecules into S22(10) networks
