N,N'-{[Ethane-1,2-diylbis(-oxy)]bis-(ethane-2,1-di-yl)}bis-(4-methyl-benzene-sulfonamide).

The asymmetric unit of the title compound, C(20)H(28)N(2)O(6)S(2), contains one half-mol-ecule, related to the other half by a twofold rotation axis. The two aromatic rings of the mol-ecule make a dihedral angle of 50.91 (7)°. The O-CH(2)-CH(2)-O and N-CH(2)-CH(2)-O fragments both adopt gauche conformations, with torsion angles of 76.0 (4) and 70.4 (3)°, respectively. In the crystal, adjacent mol-ecules are linked through N-H⋯O hydrogen bonds into chains along the a-axis direction. The chains are further connected via C-H⋯O inter-actions into a two-dimensional supra-molecular network in the ac plane.
