The complete mol-ecule of the title compound, C20H 20N2O4S2, is generated by crystallographic twofold symmetry, with two C atoms lying on the rotation axis. The dihedral angle between the central benzene ring and the pendant ring is 68.42 (6)° and the dihedral angle between the pendant rings is 45.11 (5)°. The torsion angles for the C - S - N - C and S - N - C - C fragments are -73.22 (15) and -150.45 (13)°, respectively. In the crystal, mol-ecules are linked by N - H⋯O hydrogen bonds, generating corrugated (001) sheets. Aromatic π-π stacking [centroid-centroid separation = 3.8925 (12) and 3.9777 (12) Å] and weak C - H⋯O inter-actions also occur.
