title: N,N'-Bis(2-chloro-phen-yl)succinamide.
abstract: There is one half-mol-ecule in the asymmetric unit of the title compound, C(16)H(14)Cl(2)N(2)O(2), with a center of symmetry at the mid-point of the central C-C bond. The N-H and C=O bonds in the C-NH-C(O)-C fragment are anti to each other and the amide O atom is anti to the H atoms attached to the adjacent C atoms. However, the conformation of the N-H bond in the amide fragments is syn to the ortho-chloro groups in the adjacent benzene rings. The dihedral angle between the benzene ring and the NH-C(O)-CH(2) fragment is 47.0 (2)°. In the crystal, a series of N-H⋯O inter-molecular hydrogen bonds link the mol-ecules into chains along the b axis.
