2-Chloro-5-(2-iodo-benzene-sulfonamido)-benzoic acid.

ABSTRACT: In the mol-ecule of the title compound, C(13)H(9)ClINO(4)S, the coordination around the S atom is distorted tetra-hedral. The aromatic rings are oriented at a dihedral angle of 74.46?(9)°. Intra-molecular C-H?O hydrogen bonds result in the formation of two five- and one six-membered rings, which adopt planar, envelope and twisted conformations, respectively. In the crystal structure, inter-molecular N-H?O and O-H?O hydrogen bonds link the mol-ecules to form R(2) (2)(8) ring motifs, which are further linked by C-H?O hydrogen bonds. ?-? contacts between the benzene rings [centroid-centroid distances = 3.709?(3) and 3.772?(3)?Å] may further stabilize the structure. The I atom is disordered over two positions, refined with occupancies of ca 0.75 and 0.25.
