Abstract: In the title compound, C13H8Cl3NO4S, the aromatic rings are oriented at a dihedral angle of 68.94 (1)° and the molecule adopts a V-shape. An intramolecular N-HO interaction generates a six-membered S(6) ring motif. In the crystal, pairs of O-HO hydrogen bonds involving the carboxy group link the molecules into inversion dimers with an R22(8) motif. N-HO and non-classical C-HO interactions connect the molecules, forming sheets propagating in (100).
