The asymmetric unit of the title compound, C(14)H(14)N(2)O(4)S, consists of two crystallographically independent mol-ecules. The mol-ecules are twisted at the S-N bonds with C-S-N-C torsion angles of 44.2 (3) and -49.3 (3)°. The dihedral angles between the benzene rings in the two mol-ecules are 71.53 (7) and 72.11 (7)°. The amide H atoms exhibit bifurcated intra- and inter-molecular hydrogen bonds; the intra-molecular N-H⋯O(N) hydrogen bonds generate S(7) motifs. In the crystal, the independent mol-ecules are separately connected through the inter-molecular N-H⋯O(S) hydrogen bonds, generating a C(4) motif and a helical chain along the b axis for one mol-ecule and an R(2) (2)(8) motif and an inversion dimer for the other. The crystal studied was a pseudo-merohedral twin with twin law (-100/0-10/001), the refined ratio of the twin domains being 0.7876 (12):0.2124 (12).
