Molecular recognition and the design of solid state structures: protonation-induced conformational change and self-assembly of 2,6-diamidopyridinium phosphates

Abstract

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.
