The well-known hydrogen-bonded ladder displayed by amides in the solidstate, is readily disrupted and reduced to an R22(8) motif if a competitive hydrogen-bond acceptor is incorporated in the molecularstructure of the amide. When a weaker hydrogen-bond acceptor (i.e. –NO2, –CN, –Cl, –Br) is present, the ladder persists in about every other case, whereas if a stronger hydrogen-bond acceptor is introduced
