Abstract: From an aqueous solution of racemic 2,3-dibromosuccinic acid and (R)-1-phenylethanamine, crystals of the title compound, C8H12N+·0.5C4H2Br2O42-·0.5C4H4Br2O4·H2O, were obtained in almost quantitative yield. The structure contains both enantiomers of the starting material, dibromosuccinic acid. The S,S enantiomer is present as a dianion and the R,R enantiomer as the neutral acid; both of these components lie on twofold rotation axes. The structure features a complex two-dimensional network of hydrogen bonds.
