Benzyl­ammonium hexa­noate

A binary mixture of benzyl­amine and hexa­noic acid has been reacted to form the title salt, C₇H₁₀N⁺·C₆H₁₁O₂^-. This crystal has a 1:1 stoichiometry of acid- and amine-derived species which contrasts with other related species which can have a number of other integer ratios of acid and amine components. The diffraction data indicate complete transfer of a proton from the acid to the amine to give the salt, comprising a cation and anion combination, with the formation of three hydrogen bonds around each ammonium group. This contrasts with other related species.

(S)-(−)-1-Phenyl­ethanaminium hexa­noate

A binary mixture of (S)-(−)-1-phenyl­ethanamine and hexa­noic 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.
