The title compound, 3,3'-(4-pyridylimino)dipropanenitrile, C(11)H(12)N(4), has a twofold axis and consists of a pyridine ring head and two cyanoethyl tails, the three groups being linked by an N atom. The planar geometry around the amino N atom suggests conjugation with the pi-system of the pyridine ring. The molecules are stacked in a layer structure via relatively weak to very weak intermolecular C-H.pi and C-H.N hydrogen-bond interactions.
