N-(2-Amino-5-chlorophenyl)-2-bromobenzenesulfonamide

In the title compound, C12H10BrClN2O2S, the sulfonamide group adopts a staggered conformation about the N—S bond [the C—S—N—H torsion angle is 97 (3) ] with the N-atom lone pair bisecting the O S O angle. For the C(Ar)—S bond, the ortho-substituted C atom bisects one of O S–N angles [the C—C—S—N torsion angle is 57.7 (3) ]. The mean planes of the aromatic rings form a dihedral angle of 75.1 (1) . In the crystal, molecules form inversion dimers through pairs of N—H NH2 hydrogen bonds. The molecules are further consolidated into layers along the bc plane by weaker N—H O interactions.
