Abstract: In the title compound, C₁₉H₁₂F₆O, a monoketone derivative of curcumin, both double bonds have a trans conformation. The molecule is mostly planar with all C and O atoms essentially coplanar, with the exception of one benzene ring, which is tilted by 17.18 (1)° with respect to the plane of the remainder of the molecule. The r.m.s. deviation from planarity of the coplanar section is 0.0097 Å. The crystal packing features weak C-HO and C-HF interactions.
