Abstract: | The central ring of the anthrone system in the title compound, C17H14O4, has a shallow envelope conformation, and each of the two outer rings is inclined at an angle of 17.41 (3)°. In the solid state, the molecules exist as centrosymmetrically related O—H⃛O hydrogen‐bonded dimers. Two intramolecular O—H⃛O hydrogen bonds, involving the central carbonyl O atom and having a graph‐set motif of S(6), are observed. These intramolecular interactions lead co‐operatively to an O—H⃛O⃛H—O pattern that has a binary graph‐set motif of (10). |
