Abstract

The complete mol­ecule of the title compound, C20H19NO5S2, is generated by a crystallographic twofold axis and the O atom and N—H group attached to the central benzene ring are statistically disordered. The dihedral angle between the central and terminal benzene rings is 56.91 (5)° and that between the terminal benzene rings is 29.80 (5)°. In the crystal, N—H⋯O hydrogen bonding links the mol­ecules into sheets lying parallel to the ab plane.
