4-Chloro-N-phenylbenzenesulfonamide

Abstract: In the crystal of the title compound, C12H10ClNO2S, the asymmetric unit contains two independent molecules. The N-C bonds in the C-SO2-NH-C segments have gauche torsions with respect to the S=O bonds. The molecules are twisted at the S atoms with C-SO2-NH-C torsion angles of -53.8 (3) and -63.4 (3)° in the two molecules. The benzene rings are tilted relative to each other by 69.1 (1) and 82.6 (1)°. The dihedral angle between the sulfonyl benzene rings of the two independent molecules is 23.7 (2)°. The crystal structure features inversion-related dimers linked by N-H...O hydrogen bonds.
