Hydrogen-bonded dimers of 1,8,10-trihydroxy-10-(prop-2-enyl)anthracen-9(10H)-one:S(6),R^{\bf 1}_{\bf 2}(10) andR^{\bf 2}_{\bf 2}(14) motifs
摘要:
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) 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).
