摘要：

Di(pyrid-2-yl)amine is monoprotonated by acetic, squaric as well as hydrochloric acid and diprotonated by trifluoromethylsulfonic acid. To explore the anion and hydrogen-bridge dependency of its salts, crystals of the monomeric tetraphenylborate, the dimeric squarate as well as the bis(trifluoromethylsulfonate) and the polymeric chloride hydrate have been grown and their structures determined: Separated by bulky tetraphenylborate anions, pyrid-2-yl(2'-pyridinium) amine cation contains an intramolecular hydrogen bridge (NH)-H-circle plus ... N and is slightly folded. The squarate salt dimer exhibits additional bridges, N-H ... O-circle minus and O-H ... O. The severely twisted di(2-pyridinium)amine dication is connected to its trifluoromethylsulfonate counter anions by altogether three H-bridges, two (NH)-H-circle plus ... O and one N-H ... O. The chloride dihydrate crystallizes in layers of 16-membered rings, formed from three Cl anions and five water molecules. The diversity of the hydrogen-bridge dominated salt structures is discussed based on comparison with selected literature examples and on PM3 calculations.
