Abstract

MA-Aib₆ forms discrete stacks with sandwiched water, sodium and nitrate ions, presenting a novel profile, where nine out of the 12 binding sites, of the six amides present, are involved in bonding with water, sodium and nitrate ions, with no inter-amide hydrogen bonding. This is the first example of the stacking of a benzenehexacarboxylic acid core.
