Molecules of the title compound, C 21 H 30 N 2 O 6 S 2 , adopt a skeletal conformation which does not possess even approximate internal symmetry. The molecules are linked by two N—H⋯O=S hydrogen bonds [H⋯O = 1.97 Å (×2), N⋯O = 2.865 (2) and 2.864 (2) Å, and N—H⋯O = 160 and 159°] into molecular ladders, alternatively described as chains of edge‐fused (20) rings.
