Ascertaining the 1D Hydrogen-Bonded Network in Organic Ionic Solids

Crystal engineering concepts are exploited to generate a 1D hydrogen-bonded network in a series of
organic salts (9−18) derived from dicyclohexylamine and various dicarboxylic acids (1−7) having linear as well as
twisted/angular functional topology. It is clearly demonstrated that the cyclic 0D hydrogen-bonded network involving
corresponding cations and anions in a secondary ammonium monocarboxylate salt (synthon B or C) can indeed be
transformed into a 1D network in 1:2 (acid/amine) dicarboxylate systems (9−12). The effects of the twisted/angular
functional topology of the anion moiety on the resultant supramolecular architectures in the corresponding 1:2 (acid/amine) salts (13−15) are examined. The 1:1 salts (16−18) of the dicarboxylic acids having twisted/angular functional
topology also display a 1D network.
