3-Allyl-2-hydroxy-5,6,8-trimethoxynaphthalene-1,4-dione

In the crystal structure of the title compound, C16H16O6, a pair of naphthoquinone rings are linked via O—H...O—C hydrogen bonds in a nearly orthogonal arrangement. This dimeric unit is linked to a neighbouring dimer by π–π stacking interactions between the naphthoquinone rings, where the distance between the mean plane of the naphtoquinone backbones is 3.468 , and O—H...O—C hydrogen bonds.
