Rac-2-Amino-pyridinium cis-2-carb-oxy-cyclo-hexane-1-carboxyl-ate.

ABSTRACT: In the structure of the title compound, C(5)H(7)N(2) (+)·C(8)H(11)O(4) (-), the cis anions associate through head-to-tail carb-oxy-lic acid-carboxyl O-H?O hydrogen bonds [graph set C(7)], forming chains which extend along c and are inter-linked through the carboxyl groups, forming cyclic R(2) (2)(8) associations with the pyridinium and an amine H-atom donor of the cation. Further amine-carboxyl N-H?O inter-actions form enlarged centrosymmetric rings [graph set R(4) (4)(18)] and extensions down b, giving a three-dimensional structure.
