title: 2-Amino-pyridinium 1-phenyl-cyclo-propane-1-carboxyl-ate.
abstract: In the title salt, C(5)H(7)N(2) (+)·C(10)H(9)O(2) (-), 2-amino-pyridine and 1-phenyl-cyclo-propane-1-carb-oxy-lic acid crystallize together, forming a 2-amino-pyridinium-carboxyl-ate supra-molecular heterosynthon involving two N-H⋯O hydrogen bonds, which in turn dimerizes to form a four-component supra-molecular unit also sustained by N-H⋯O hydrogen bonding. A C-H⋯π inter-action between a pyridine C-H group and the centroid of the phenyl ring of the anion further stabilizes the four-component supra-molecular unit. The overall crystal packing also features C-H⋯O inter-actions.
