2-(4-Acetamidobenzenesulfonamido)benzoic acid

Abstract

In the title compound, C15H14N2O5S, two similar molecules comprise the asymmetric unit, which are linked by strong intermolecular C—H...π interactions. Both molecules are bent, with dihedral angles of 71.94 (16) and 74.62 (15)° between the benzene rings. An intramolecular N—H...O hydrogen bond occurs in each molecule. In the crystal, intermolecular N—H...O and O—H...O hydrogen bonds link the molecules into a three-dimensional network.
