title: 4-Amino-pyridinium cis-2-carb-oxy-cyclo-hexane-1-carboxyl-ate.
abstract: In the structure of the title molecular salt, C(5)H(7)N(2) (+)·C(8)H(11)O(4) (-), the cis monoanions associate through short O-H⋯O hydrogen bonds in the carb-oxy-lic acid groups [graph set C(7)], forming zigzag chains which extend along the c axis. These are inter-linked through pyridinium and amine N-H⋯O hydrogen bonds, giving a three-dimensional network structure.
