3-Hydr­oxy-1,2-dimethoxy­anthraquinone

The title compound, C(16)H(12)O(5), was isolated from Morinda officinalis How. The anthraquinone ring system is almost planar, the dihedral angle between the two benzene rings being 1.12 (4)°. In the crystal structure, O—H⋯O and C—H⋯O hydrogen bonds link the mol­eculesin the crystallographic a-axis...

Sumario:The title compound, C(16)H(12)O(5), was isolated from Morinda officinalis How. The anthraquinone ring system is almost planar, the dihedral angle between the two benzene rings being 1.12 (4)°. In the crystal structure, O—H⋯O and C—H⋯O hydrogen bonds link the mol­eculesin the crystallographic a-axis direction. Weak π–π stacking inter­actions [centroid–centroid distance between symmetry-related benzene rings of 3.699 (4) Å] are also present.
