( E )-3-(2,5-Difluorophenyl)-1-phenylprop-2-en-1-one
The title chalcone derivative, C 15 H 10 F 2 O, is almost planar, with the benzene ring being inclined to the phenyl ring by 7.45 (9)°. The conformation about the C=C bond is E . In the crystal, molecules are linked by two pairs of C—H...F hydrogen bonds, forming inversion dimers enclosing R 2 2 (8)...
