The crystal structure of a new polymorph of the title compound, C 8 H 12 N + ·C 10 H 11 O 2 − , 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.
