## Abstract **BACKGROUND:** (__R__)‐(‐)‐Mandelic acid (__R__‐MA) is an important intermediate and chiral regent with broad uses. An efficient method for the separation of __R__‐MA from the bioreaction mixture with high yield is of great importance, thus, the main objective of this work is to invest
From an aqueous solution of racemic 2,3-dibromosuccinic acid and (__R__)-1-phenylethanamine, crystals of the title compound, C~8~H~12~N^+^·0.5C~4~H~2~Br~2~O~4~ ^2−^·0.5C~4~H~4~Br~2~O~4~·H~2~O, were obtained in almost quantitative yield. The structure contains both enantiomers of the starting materia
