چکیده
In the title compound, C(14)H(15)N(3), the diethyl-amino N atom, benzene ring, olefinic bond and cyano groups form an extended conjugated system, making the mol-ecule 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 diethyl-amino N atom and the two attached ethyl C atoms is 9.51 (14)°. In the crystal, inter-molecular C-H⋯π inter-actions stabilize the packing.
