5-Hy­droxy-7-meth­oxy-2-methyl-4H-chromen-4-one from Dysoxylum macrocarpum (Meliaceae)

Both independent mol­ecules in the asymmetric unit of the title compound, C(11)H(10)O(4), are almost planar (r.m.s. deviations = 0.011 and 0.033 Å). In both mol­ecules, the hy­droxy group is intra­molecularly hydrogen bonded to the ketonic O atom. The independent mol­ecules are stacked alternately a...

description Both independent mol­ecules in the asymmetric unit of the title compound, C(11)H(10)O(4), are almost planar (r.m.s. deviations = 0.011 and 0.033 Å). In both mol­ecules, the hy­droxy group is intra­molecularly hydrogen bonded to the ketonic O atom. The independent mol­ecules are stacked alternately along the a axis, with the centroids of their chromene ring separated by distances of 4.490 (1) and 3.621 (1) Å.
