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