N,N′-(1,4-Phenyl­ene)bis­(4-chloro­butanamide)

The title mol­ecule, C₁₄H₁₈Cl₂N₂O₂, lies on a crystallographic inversion center and the each 4-chloro­butanamide group adopts an anti-staggered conformation. In the crystal, adjacent mol­ecules are linked through N—H...O contacts, forming infinite ribbons extending parallel to the a axis.
