摘要：

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)degrees 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 (A) over circle. The crystal packing features weak C-H center dot center dot center dot O and C-H center dot center dot center dot F interactions.
