2-(4-Bromo-benzene-sulfonamido)benzoic acid.

ABSTRACT: In the title compound, C(13)H(10)BrNO(4)S, 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.

In the title compound, C(13)H(10)BrNO(4)S, 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. ...[more]

Project description:The title compound, C(13)H(10)BrNO(4)S, belongs to the sulfonamide class of organic compounds. The two aromatic rings are inclined at 34.30 (15)° to one another, and the carboxyl substituent lies in the plane of the benzene ring to which it is bound (maximum deviation = 0.004 Å). In the crystal structure, charactersitic carboxylic acid dimers are formed through O-H⋯O hydrogen bonds. These dimers are linked into rows down a by N-H⋯O inter-actions. Additional C-H⋯O contacts further stabilize the structure, and a close Br⋯Br(x, -y + 1, -z + 1) contact of 3.5199 (9) Å is also observed.
