title: The 1:1 adduct of Kemp's triacid with 2-aminopyridine
abstract: The crystal structure determination of the molecular proton-transfer adduct of Kemp's triacid (cis-cis-1,3,5-trimethylcyclohexane-1,3, 5-tricarboxylic acid, KTA) with 2-aminopyridine (2-APY), namely 2-aminopyridinium 3,5-dicarboxy-1,3, 5-trimethylcyclohexanecarboxylate, 2-APY(+).KTA(-) or C(5)H(7)N(2)(+).C(12)H(17)O(6)(-), has revealed a centrosymmetric hydrogen-bonded cyclic KTA homodimer repeating unit [O.O 2.524 (4) A] linked into a polymer structure through the pyridinium and amino groups of the 2-APY molecule [O.N 2.736 (4), 2.989 (4) and 2.999 (4) A].
