Experimental Crystal data

R factor = 0.039; wR factor = 0.095; data-to-parameter ratio = 12.4. In the title compound, C13H9ClN2O5S, the dihedral angle between the benzene rings is 74.86 (11). The molecule is twisted at the S atom, with a dihedral angle of 82.53 (13) between the sulfonyl benzene ring and the S—N—C O segment. In the crystal, molecules are linked into inversion dimers through pairs of N—H O hydrogen bonds, thereby forming R2 2(8) loops. Molecules are linked into C(7) [010] chains by weak C—H O hydrogen bonds, and C—H interactions are also observed. Related literatur
