title: Hydrogen-bonded dimers of 1,8,10-trihydroxy-10-(prop-2-enyl)anthracen-9(10H)-one: S(6), R(2)(1)(10) and R(2)(2)(14) motifs.
abstract: The central ring of the anthrone system in the title compound, C(17)H(14)O(4), has a shallow envelope conformation, and each of the two outer rings is inclined at an angle of 17.41 (3) degrees. In the solid state, the molecules exist as centrosymmetrically related O-H.O hydrogen-bonded dimers. Two intramolecular O-H.O 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-H.O.H-O pattern that has a binary graph-set motif of R(2)(1)(10).
