N,N′-Bis(phenyl­sulfon­yl)succinamide

In the crystal structure of the title compound, C(16)H(16)N(2)O(6)S(2), the conformation of the N—C bonds in the C—SO(2)—NH—C(O)—C segments have gauche torsions with respect to the S=O bonds, while the conformations of the N—H and C=O bonds in the amide fragments are trans to each other and the amide O atom is anti to the H atoms attached to the adjacent C atom. The mol­ecule is bent at the S atom with a C—SO(2)—NH—C(O) torsion angle of 65.2 (2)°. The molecule lies about a centre of inversion. The dihedral angle between the benzene ring and the SO(2)—NH—C(O)—C(2) segment in the two halves of the mol­ecule is 77.4 (1)°. The structure exhibits both intra­molecular and inter­molecular hydrogen bonds. A series of N—H⋯O(S) hydrogen bonds links the mol­ecules into infinite chains.
