title: N,N'-Bis(2-chloro-phenyl-sulfon-yl)adipamide.
abstract: In the centrosymmetric title compound, C(18)H(18)Cl(2)N(2)O(6)S(2), the conformation of the N-H and C=O bonds in the C-SO(2)-NH-C(O)-C-C segment is anti to each other. The dihedral angle between the planes of the benzene ring and the central part of the molecule is 89.6 (2)°. In the crystal, inter-molecular N-H⋯O(S) hydrogen bonds link the mol-ecules into sheets along the b axis.
