The role of hydrogen bonding in the crystalpacking of a series of 4-aminoperfluoropyridines was studied using single-crystal X-ray crystallography. The aminoperfluoropyridines were synthesized using only excess amine to serve as both nucleophile and base. Instead of addition to the perfluoropyridine ring, a strong N–H···F–C hydrogen bond led to cocrystal formation of perfluoropyridine with sterically
