Molecules of the title compound, C8H7NO5S, are linked into sheets by a combination of two-centre hydrogen bonds, one of type O-H...O [H...O = 1.81 Angstrom, O...O = 2.648 (2) Angstrom and O-H...O = 173degrees] and three of type C-H...O [H...O = 2.40-2.48 Angstrom, C...O = 3.206 (3)-3.391 (3) Angstrom and C-H ... O = 131-160degrees]. These sheets are linked by an unusual three-centre C-H...(O)(2) hydrogen bond [H...O = 2.46 and 2.56 Angstrom, C...O = 3.289 (3) and 3.351 (3) Angstrom, and C-H...O = 141 and 137degrees], in which the two acceptors are carboxyl and sulfoxide O atoms.
