Abstract

The title compound, C(16)H(13)FO, adopts an E configuration with respect to the C=C bond of the propenone unit. The dihedral angle between the two benzene rings is 47.0 (5)°. Intra-molecular C-H⋯O hydrogen bonds generate an S(5) ring motif. In the crystal structure, mol-ecules are packed into columns along the c axis and the structure is stabilized by weak intra-molecular C-H⋯O hydrogen bonds and inter-molecular C-H⋯π inter-actions involving both aromatic rings.
