Interplay of phenyl-perfluorophenyl stacking, C-H⋯F, C-F⋯π and F⋯F interactions in some crystalline aromatic azines

Abstract

Analysis of phenyl-perfluorophenyl stacking synthon, C-H⋯F, C-F⋯π interactions, and F⋯F tetramer in three closely related azine crystal structures shows the dominance of Ar-ArF synthon while other interactions are turned on/off depending on the H/F stoichiometry in the molecule. © 2002 The Royal Society of Chemistry.
