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.
在标题盐C(5)H(7)N(2) (+)·C(10)H(9)O(2) (-)中，2-氨基吡啶与1-苯基-环丙烷-1-羧酸共同结晶，形成一个涉及两个N-H⋯O氢键的2-氨基吡啶鎓羧酸盐超分子异合成子，该异合成子进而二聚形成一个同样由N-H⋯O氢键维持的四组分超分子单元。吡啶C-H基团与阴离子苯环质心之间的C-H⋯π相互作用进一步稳定了四组分超分子单元。整体晶体堆积还具有C-H⋯O相互作用。
