Abstract

In the title compound, C15H2F10O, the two perfluorinated arene rings are tilted at an angle of 66.08 (5)° with respect to each other. The olefinic double bond adopts an E configuration and the single bond between the olefinic and carbonyl double bonds has an s-trans conformation. The carbonyl group is not in a coplanar alignment with respect to the neighbouring arene ring (0.963 Å from aryl plane) while being coplanar with regard to the olefinic double bond (0.0805 Å from olefinic bond). The crystal packing does not feature significant hydrogen-bond-type or stacking interactions.

Highlights

C15H2F10O, the two perfluorinated arene rings are tilted at an angle of 66.08 (5) with respect to each other
Comment The title compound (Fig. 1) exhibits a non-planar structure, that can be described by dihedral and torsional angles realting the arene rings and the carbonyl group to each other
The carbonyl group is tilted with reference to the adjacent perfluoro arene unit showing a torsional angle O1—C9—C10—C15 of 60.3 (2)°
