The title compound, C18H16N2, crystallizes with Z′ = . The mol-ecule exhibits 222 symmetry, with its centre at the inter-section of three twofold axes, one of which traverses the mol-ecule through the nitrile groups and the ipso and para ring atoms. The torsion angle between the rings is 50.3 (1)°. Adjacent mol-ecules are involved in anti-parallel CN⋯CN inter-actions and weak C - H⋯N hydrogen bonds.
