3-Acetyl-5-hy­droxy-2-methyl­anthra[1,2-b]furan-6,11-dione

The asymmetric unit of the title compound, C(19)H(12)O(5), contains two independent mol­ecules, both slightly buckled along an axis passing through the C=O bonds of the anthraquinone ring system (r.m.s. deviation of non-H atoms = 0.082 and 0.148 Å): the benzene rings are twisted to each other by 4.3...

description The asymmetric unit of the title compound, C(19)H(12)O(5), contains two independent mol­ecules, both slightly buckled along an axis passing through the C=O bonds of the anthraquinone ring system (r.m.s. deviation of non-H atoms = 0.082 and 0.148 Å): the benzene rings are twisted to each other by 4.3 (3)°in one mol­ecule and 10.6(3)° in the other. In both mol­ecules, the hy­droxy group forms an intra­molecular O—H⋯O hydrogen bond. The two independent mol­ecules inter­act by π–π stacking with a centroid–centroid distance of 3.539 (2) Å between hy­droxy­benzene rings of adjacent mol­ecules.
