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

Publication Date Jul 22, 2022


The title molecule, C17H15FO2, 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.
