Abstract

In the title compound, C22H24N2O4S2, the dihedral angles between the central benzene ring and the pendant rings are 66.96 (13) and 69.37 (13)°. The torsion angles for the C—N—S—C fragments are −68.5 (3) and −72.6 (3)°. In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds to generate infinite (001) sheets containing R44(28) loops. A weak aromatic π–π stacking contact between one of the terminal benzene rings and its inversion-related partner is also observed [centroid-to-centroid separation = 3.796 (2) Å and slippage = 1.581 Å], as are two possible C—H⋯π contacts.
