چکیده
The title mol-ecule, C(14)H(18)Cl(2)N(2)O(2), lies on a crystallographic inversion center and the each 4-chloro-butanamide group adopts an anti-staggered conformation. In the crystal, adjacent mol-ecules are linked through N-H⋯O contacts, forming infinite ribbons extending parallel to the a axis.
