Jun-Da Huang, and Qin-Qin Tang, and Xiao-Yan Chen, and Yun Ye, and Yi Wang

The mol-ecule of the title compound, C(17)H(10)F(4)O, is roughly planar, with a dihedral angle of 5.59 (14)° between the two phenyl rings. The mol-ecule has an E conformation with respect to the olefinic bonds. In the crystal, mol-ecules 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.
