The title mol-ecule, CHFO, was synthesized by a Claisen-Schmidt condensation with 4-fluoro-benzaldehyde and 4'-eth-oxy-aceto-phenone. The torsion angles between the 4-fluoro-phenyl ring and the alkene and the 4'-eth-oxy-phenyl ring and the 2-propen-1-one are -1.2 (4) and 1.2 (3)°, respectively; however, there is a larger torsion between the bonds comprising the 2-propen-1-one unit of 12.0 (4)°. The crystal packing is stabilized by inter-molecular C-H⋯O/F hydrogen bonding, π-π stacking, and H-π inter-actions.
标题分子CHFO是通过4-氟苯甲醛与4'-乙氧基苯乙酮的克莱森-施密特缩合反应合成的。4-氟苯环与烯烃之间以及4'-乙氧基苯环与2-丙烯-1-酮之间的扭转角分别为-1.2（4）°和1.2（3）°；然而，构成2-丙烯-1-酮单元的键之间存在较大的扭转角，为12.0（4）°。晶体堆积通过分子间C-H⋯O/F氢键、π-π堆积和H-π相互作用得以稳定。
