ABSTRACT: The title compound, C14H12ClNO4S, crystallizes with two mol-ecules in the asymmetric unit. The dihedral angles between the benzene rings are 89.68?(1) (mol-ecule 1) and 82.9?(1)° (mol-ecule 2). In each mol-ecule, intra-molecular N-H?O hydrogen bonds between the amide H atom and the meth-oxy O atom generate S(6) loops. In the crystal, mol-ecule 2 is linked into inversion dimers through pairs of C-H?O inter-actions, forming an R 2 (2)(8) ring motif. Mol-ecules 1 and 2 are further linked along the b-axis direction through C-H?? inter-actions. The crystal structure is further stabilized by several ?-? stacking inter-actions [centroid-centroid separations = 3.7793?(1), 3.6697?(1) and 3.6958?(1)?Å], thus generating a three-dimensional architecture.
