The crystal structure of C16H36+.PF 6-, was analyzed at 110K. It was observed that the ammonium cation and PF6- anion display perfectly ordered conformations. The PF6- anion is completely disordered at 213K, and it exhibits large-amplitude liberation or partial dynamic disorder at 173 K. The crystal structure of the compound can be described as composed of sheets of alternating cations and anions stabilized by coulombic as well as by van der Waals interactions.
