title: 1,5-Bis(penta-fluoro-phen-yl)-3-phenyl-pent-2-ene-1,5-dione.
abstract: In the title compound, C(23)H(8)F(10)O(2), the three arene rings are twisted one with respect to the other: the two perfluorinated arene rings are tilted to each other by an angle of 60.39 (7)°. They are inclined to the non-fluorinated phenyl unit by 38.85 (7) and 78.74 (7)°. The olefinic double bond adopts an E configuration. The carbonyl groups are not in a coplanar alignment with reference to the neighbouring arene rings. The crystal packing features a number of weak C-H⋯F inter-actions, which leads to the formation of a three-dimensional network.
