N,N′-Bis(2,5-dichloro­phen­yl)isophthalamide

Abstract

The asymmetric unit of the title compound, C(20)H(12)Cl(4)N(2)O(2), contains one half-mol-ecule with a center of symmetry along a C⋯C axis of the central benzene ring. The two C=O groups adopt an anti orientation and the two amide groups are twisted away from the central benzene ring by 27.38 (3) and 27.62 (4)°. The mean planes of the dichloro-substituted benzene rings are twisted by 7.95 (4)° with respect to the benzene ring. The crystal packing is stabilized by weak inter-molecular N-H⋯O inter-actions.
