2-(4-Bromobenzenesulfonamido)benzoic acid

Abstract

In the title compound, C13H10BrNO4S, the dihedral angle between the benzene rings is 82.75 (15)°. An intra-molecular N - H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, two mol-ecules form an R 2 2(8) centrosymmetric dimer through a pair of O - H⋯O hydrogen bonds. Intra- and inter-molecular C - H⋯O hydrogen bonds are also observed.
