Eucomic acid methanol monosolvate

Abstract

In the crystal structure of the title compound [systematic name: 2-hydroxy-2-(4-hydroxybenzyl)butanedioic acid methanol monosolvate], C11H12O6·CH3OH, the dihedral angles between the planes of the carboxyl groups and the benzene ring are 51.23 (9) and 87.97 (9)°. Intermolecular O—H...O hydrogen-bonding interactions involving the hydroxy and carboxylic acid groups and the methanol solvent molecule give a three-dimensional structure.
