2-[4-(Diethylamino)benzylidene]malononitrile

Abstract

In the title compound, C14H15N3, the diethylamino N atom, benzene ring, olefinic bond and cyano groups form an extended conjugated system, making the molecule nearly planar: the dihedral angle between the benzene ring and the best plane throught the cyano groups is 4.93 (10)°, while the dihedral angle between the benzene ring and the plane through the diethylamino N atom and the two attached ethyl C atoms is 9.51 (14)°. In the crystal, intermolecular C—H...π interactions stabilize the packing.
