Abstract: 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-HO hydrogen-bond interactions link the molecules into S22(10) networks.
