Published: June 2009

In the title complex, C(17)H(12)N(2), the non-aromatic six-membered ring adopts an envelope conformation. The dihedral angle between the eight-membered plane containing the malononitrile group and the aromatic system is 25.88 (4)°. The distance from the central C atom of the malononitrile group to the centroid of the n-glide-related distal aromatic ring is 3.66 Å, suggesting π-π inter-actions.
