Abstract: The asymmetric unit of the title compound, C12H8N2O6S, an important diphenyl sulfone derivative, contains one half-molecule; a mirror plane passes through the SO2 group. The dihedral angle between the two symmetry-related benzene rings is 40.10 (13)°. An intramolecular C-H...O hydrogen bond results in the formation of a five-membered ring, which adopts an envelope conformation.
