title: 5-Hy-droxy-7-meth-oxy-2-methyl-4H-chromen-4-one from Dysoxylum macrocarpum (Meliaceae).
abstract: Both independent mol-ecules 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 mol-ecules, the hy-droxy group is intra-molecularly hydrogen bonded to the ketonic O atom. The independent mol-ecules 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.
