چکیده
The complete mol-ecule of the title compound, C(20)H(20)N(2)O(4)S(2), 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.
