A binary mixture of (S)-(-)-1-phenyl-ethanamine and hexa-noic acid was allowed to react to form the title salt, C8H12N(+)·C6H11O2(-). This crystal contains a 1:1 stoichiometric mixture of the acid- and amine-derived species and displays a chiral structure with N-H⋯O hydrogen-bonded chains propagating along the c-axis direction.
