Abstract

The mol­ecule of the title compound, C17H10F4O, is roughly planar, with a dihedral angle of 5.59 (14)° between the two phenyl rings. The mol­ecule has an E conformation with respect to the olefinic bonds. In the crystal, mol­ecules are connected through C—H⋯O hydrogen bonds and there is slipped π–π stacking [centroid–centroid distance = 3.7983 (18), slippage =1.309 ;Å] between symmetry-related benzene rings.
