Abstract: The crystal structure of a new polymorph of the title compound, C₈H₁₂N⁺·C₁₀H₁₁O₂^-, was solved by simulated annealing from laboratory X-ray powder diffraction data, collected at 295 K. Subsequent Rietveld refinement using data collected to 1.54 Å resolution, yielded an R_wp of 0.030. The compound crystallizes with one (R)-1-phenylethylammonium cation and one (R)-2-phenylbutyrate anion in the asymmetric unit.
