N,N'-Propylenedioxybis(2,4,6-trimethylbenzenesulfonamide): molecules of unexpected conformation form a molecular ladder built from two independent N-H...O=S hydrogen bonds.
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 A (x2), N...O = 2.865 (2) and 2.864 (2) A, and N-H...O = 160 and 159 degrees] into molecular ladders, alternatively described as chains of edge-fused R(2)(2)(20) rings.
