title: 2-benzenesulfonamidobenzoic Acid.
abstract: In the title compound, C(13)H(11)NO(4)S, the dihedral angle between the planes of the benzene ring and the carboxyl group is 13.7 (1)°. The mol-ecular structure contains intra-molecular N-H⋯O and C-H⋯O hydrogen-bonding inter-actions, while the crystal packing is stabilized by C-H⋯O and O-H⋯O hydrogen bonds and C-H⋯π inter-actions. The O-H⋯O hydrogen bonds form a cyclic dimer, with graph-set motif R(2) (2)(8), about a centre of symmetry.
