N-[(2-Chlorophenyl)sulfonyl]-2-methoxybenzamide

Abstract

The title compound, C14H12ClNO4S, crystallizes with two molecules in the asymmetric unit. The dihedral angles between the benzene rings are 89.68(1) (molecule 1) and 82.9(1)° (molecule 2). In each molecule, intramolecular N - H⋯O hydrogen bonds between the amide H atom and the methoxy O atom generate S(6) loops. In the crystal, molecule 2 is linked into inversion dimers through pairs of C - H⋯O interactions, forming an R22(8) ring motif. Molecules 1 and 2 are further linked along the b-axis direction through C - H⋯π interactions. The crystal structure is further stabilized by several π-π stacking interactions [centroid-centroid separations = 3.7793(1), 3.6697(1) and 3.6958(1)Å], thus generating a three-dimensional architecture.
