The molecule CHFO was created using a Claisen-Schmidt condensation involving 4-fluoro-benzaldehyde and 4'-ethoxy-acetophenone.
The torsion angles between its components are very small, indicating a relatively planar structure, with the largest torsion being between bonds in the 2-propen-1-one unit at 12.0°.
The stability of the crystal structure arises from various interactions, including hydrogen bonding, π-π stacking, and H-π interactions.
