摘要
A metastable modification of (RS)-mandelic acid, C8H8O3, was obtained from an aqueous solution. The structure features hydrogen-bonded double chains of acid molecules, which run along the a axis of the crystal. The structure shows a close relationship to that of the pure enantiomer and differs significantly from the structure of the stable modification of the racemate. There are two molecules in the asymmetric unit.
