Popis:	The crystal and molecular structures of the title compound have been established by the X-ray diffraction method. The molecule has a bent configuration with a dihedral angle between the double bond planes of 43.2°. The double bonds are localized and have lengths of 1.351(6) and 1.355(6) A. However vibrational and electronic spectroscopy indicate that the conjugation in the butadiene fragment is retained; this fragment is a conductor of the direct polar conjugation effect between the donor diethylamino group and the acceptor carbonyl group.
