Crystal structure of (2E)-1-(4-eth­oxy­phen­yl)-3-(4-fluoro­phen­yl)prop-2-en-1-one

The title mol­ecule, C(17)H(15)FO(2), was synthesized by a Claisen–Schmidt condensation with 4-fluoro­benzaldehyde and 4′-eth­oxy­aceto­phenone. The torsion angles between the 4-fluoro­phenyl ring and the alkene and the 4′-eth­oxy­phenyl 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 inter­molecular C—H⋯O/F hydrogen bonding, π–π stacking, and H–π inter­actions.
