The title 1:1 stoichiometric salt, C7H10N+·C7H13O2−, is formed by proton transfer between heptanoic acid and benzylamine. This combination contrasts to the recently published 2:1 acid–amine adduct of cation, anion and neutral acid molecule from the same components [Wood & Clarke (2013). Acta Cryst. E69, o346–o347]. There are N—HO hydrogen bonds of moderate strength in the structure [the most important graph-set motifs are R24(8) and R44(12)], as well as weak C—HO interactions.
