Abstract
In the title compound, C13H11NO4S, the dihedral angle between the planes of the benzene ring and the carboxyl group is 13.7 (1)°. The molecular structure contains intramolecular N—H⋯O and C—H⋯O hydrogen-bonding interactions, while the crystal packing is stabilized by C—H⋯O and O—H⋯O hydrogen bonds and C—H⋯π interactions. The O—H⋯O hydrogen bonds form a cyclic dimer, with graph-set motif R 2 2(8), about a centre of symmetry.

Summary
Abdullah Mohamed Asiri, Mehmet Akkurt, * Salman A. C13H11NO4S, the dihedral angle between the planes of the benzene ring and the carboxyl group is 13.7 (1). The molecular structure contains intramolecular N—H O and C—H O hydrogen-bonding interactions, while the crystal packing is stabilized by C—H O and O—H O hydrogen bonds and C—H interactions. The O—H O hydrogen bonds form a cyclic dimer, with graph-set motif R22(8), about a centre of symmetry. Symmetry codes: (i) x þ 1; y; z þ 1; (ii) x þ 32; y þ 12; z þ 12; (iii) x; y þ 1; z; (iv). Cg2 is the centroid of the C7–C12 ring.
