Supramolecular control of fluorinated benzophenones in the crystalline state

Abstract

Crystal structures of three fluorinated benzophenones were determined via single crystal X-ray diffraction. The occurrence of the C–F⋯H, F⋯F, C–F⋯πF interactions in these crystal structures indicates that a base limit of fluorine atoms in the molecule seems to be necessary for successful competition with the hydrogen type of interactions.
