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...[pi] inter­actions. The crystal structure is further stabilized by several [pi]-[pi] stacking inter­actions [centroid-centroid separations = 3.7793 (1), 3.6697 (1) and 3.6958 (1) Å], thus generating a three-dimensional architecture.
