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 A, and O—H⋯O—C hydrogen bonds.
