Abstract: In the title compound, C18H14O3·0.5H2O, also known as dihydrotanshinone hemihydrate, the molecular skeleton is a nearly planar. The two molecules in the asymmetric unit are linked by O-HO hydrogen bonds involving the carbonyl groups and the solvent water molecule, forming moieties which are, in turn, linked via intermolecular - stacking interactions into a two-dimensional sheet.
