چکیده
In the title compound, C(17)H(13)FO(3), the dihedral angle between the benzene rings is 70.34 (5)°. In the crystal, molecules are linked via pairs of bifurcated C-H⋯(O,O) hydrogen bonds, forming inversion dimers. These dimers are linked via C-H⋯O and C-H⋯F inter-actions, forming a three-dimensional structure.
