A planar 2,2?-dipyridylammonium salt : Synthesis and structure

Reaction of 2,2?-dipyridylamine (DPA) with hexafluorophosphoric acid (HPF6) in methanol generates white rod-shaped crystals of HDPA.PF6,H2O. The salt is characterised by C, H and N analyses, FT-IR, 1H NMR, mass spectroscopy and molar conductance measurement. The X-ray crystal structure of the salt has been determined. The structure shows that the salt is monomeric. The amine nitrogen is strongly hydrogen bonded with oxygen atom of water. Two pyridyl rings are almost planar which is a rarity in the coordination chemistry of DPA. Semi-empirical AM1 calculation was also performed to delve into the novel situation.
