2-Amino­pyridinium 1-phenyl­cyclo­propane-1-carboxyl­ate

摘要

In the title salt, C5H7N2 ⁺·C10H9O2 ⁻, 2-amino­pyridine and 1-phenyl­cyclo­propane-1-carb­oxy­lic acid crystallize together, forming a 2-amino­pyridinium–carboxyl­ate supra­molecular heterosynthon involving two N—H⋯O hydrogen bonds, which in turn dimerizes to form a four-component supra­molecular unit also sustained by N—H⋯O hydrogen bonding. A C—H⋯π inter­action between a pyridine C—H group and the centroid of the phenyl ring of the anion further stabilizes the four-component supra­molecular unit. The overall crystal packing also features C—H⋯O inter­actions.
