5-Benzene-sulfonamido-2-chloro-benzoic acid.

ABSTRACT: In the title compound, C(13)H(10)ClNO(4)S, the dihedral angle between the aromatic ring planes is 87.07 (6)° and an intra-molecular C-H⋯O inter-action occurs. In the crystal, inversion dimers linked by two O-H⋯O hydrogen bonds arise from the carboxyl groups. N-H⋯O hydrogen bonds link the dimers into chains and short C-Cl⋯π and S-O⋯π contacts are also seen.

2-Chloro-6-(2,3-di-chloro-benzene-sulfonamido)-benzoic acid.

Project description:In the title compound, C13H8Cl3NO4S, the aromatic rings are oriented at a dihedral angle of 68.94 (1)° and the mol-ecule adopts a V-shape. An intra-molecular N-H⋯O inter-action generates a six-membered S(6) ring motif. In the crystal, pairs of O-H⋯O hydrogen bonds involving the carb-oxy group link the mol-ecules into inversion dimers with an R 2 (2)(8) motif. N-H⋯O and non-classical C-H⋯O inter-actions connect the mol-ecules, forming sheets propagating in (100).

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

Project description: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.

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

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).
