Abstract

In the crystal structure of the title compound, C(14)H(10)F(2)O, the dihedral angles between the benzene rings in the two crystallographically independent mol-ecules are 46.9 (2) and 47.6 (2)°. The mol-ecules are linked into dimers by C-H⋯F inter-actions and these dimers are further stacked into columns along the b axis by π-π inter-actions between the benzene rings [centroid-centroid distance = 3.8221 Å; the dihedral angle between the planes of these rings is 4.87 (2)°]. In addition, C-F⋯π interactions also contribute to the crystal packing (C⋯centroid distance = 3.5919 Å).
