title: 3-Allyl-2-hydr-oxy-5,6,8-trimethoxy-naphthalene-1,4-dione.
abstract: In the crystal structure of the title compound, C(16)H(16)O(6), 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 inter-actions between the naphthoquinone rings, where the distance between the mean plane of the naphtoquinone backbones is 3.468 Å, and O-H⋯O-C hydrogen bonds.
