(3E)-3-{(2E)-3-[4-(Dimethylamino)phenyl]prop-2-enylidene}-3,4-dihydro-2H-chromen-4-one
Abstract
In the title compound, C20H19NO2, the (dimethylamino)phenyl ring and the chromanone ring system are linked via an α-β unsaturated carbon bridge. The dihedral angle between the two terminal phenyl rings is 29.66 (6)°. The tetrahydro-4H-pyran-4 one ring in the chromanone moiety adopts a sofa conformation. The crystal packing is stabilized only by van der Waals forces.
