【 摘 要 】

In the title compound, C16H16O4, the five-membered ring of the indene-1,3-dione unit adopts a twist conformation, whereas the seven-membered ring adopts a twist–chair conformation. In the crystal, mol­ecules are linked by O—H⋯O hydrogen bonds, weak C—H⋯O hydrogen bonds and π–π stacking [centroid-to-centroid distance = 3.7373 (8) Å] into a three-dimensional supra­molecular architecture.
