N,N′-Bis(2-chlorophenylsulfonyl)suberamide

Abstract

In the crystal of the title compound, C20H22Cl2N2O6S2, the asymmetric unit comprises half of a mol­ecule, the remaining portion is generated via an inversion centre. The conformation of the N—H and C=O bonds in the SO2–NH–C(O)–C segment is anti. The mol­ecule is bent at the S atom with the C–SO2–NH–C(O) torsion angle being 68.16 (19)°. The dihedral angle between the plane of the benzene ring and the SO2–NH–C(O)–C segment is 77.5 (1)°. Hydrogen bonds of the type N—H⋯O(C) link mol­ecules into supra­molecular chains along the b axis.
