MOLECULAR RECOGNITION AND THE DESIGN OF SOLID-STATE STRUCTURES - PROTONATION-INDUCED CONFORMATIONAL CHANGE AND SELF-ASSEMBLY OF 2,6-DIAMIDOPYRIDINIUM PHOSPHATES
Protonation of 2,6-diamidopyridine with diaryl phosphates leads to a conformational change in the pyridine from inwardly to outwardly directed amide-NH groups and a resultant self-assembly of the anion and cation into an alternating cocrystal with a novel hydrogen bonding motif.
