Crystal structure of 1-(2,4-dihydroxy-6-methylphenyl)ethanone

Abstract

The title compound, C9H10O3, is a bioactive secondary metabolite, isolated from the endophytic fungus Nodulis-porium sp. The compound exhibits an intramolecular O-H···O hydrogen bond between the phenolic H atom and the carbonyl O atom of the adjacent acetyl group. In the crystal, molecules are linked by hydrogen bonds involving the 4-phenolic H atom and a symmetry-related carbonyl O atom of a neighboring molecule, resulting in extended supramolecular chains along the a-axis direction. Aromatic π-π stacking interactions between the nearly parallel benzene rings of adjacent chains [centroid-centroid distance = 3.7478 (8) Å] further stabilize the three-dimensional supramolecular frame-work.
