Crystal structure of the ethyl 2,4-dihydroxy-6-methylbenzoate from Illicium difengpi K.I.B et K.I.M.

Abstract

The title compound, C10H12O4, was isolated from Illicium difengpi K.I.B et K.I.M. An intramolecular O—H...O hydrogen bond stabilizes the molecular conformation. In the crystal, the compound forms offset slanted stacks of alternating inversion-related molecules along the a axis direction. Intermolecular O—H...O hydrogen bonds link the molecules into double strands parallel to the [101] direction.
