N,N′-Bis(4-methyl­phenyl­sulfon­yl)­suberamide

In the crystal structure of the title compound, C(22)H(28)N(2)O(6)S(2), the asymmetric unit contains one half mol­ecule with a center of symmetry at the mid-point of the central C—C bond. The conformations of all the N—H, C= O and C—H bonds in the central amide and aliphatic segments are anti to their adjacent bonds. The mol­ecule is bent at the S atom with an C—SO(2)—NH—C(O) torsion angle of −76.4 (3)°. The dihedral angle between the benzene ring and the SO(2)—NH—C(O) segment in the two halves of the mol­ecule is 67.2 (1)°. In the crystal, N—H⋯O(C) inter­molecular hydrogen bonds link the mol­ecules into chains along the b axis.
