6-Hy-droxy-7,8-dimethyl-chroman-2-one.

ABSTRACT: The title compound, C(11)H(12)O(3), is essentially planar, with an r.m.s. deviation of 0.179 Å from the mean plane through the 14 non-H atoms in the mol-ecule. The benzene ring and the pyranone mean plane are inclined at 13.12 (6)° to one another and the pyran-one ring adopts a flattened chair conformation. In the crystal, O-H⋯O hydrogen bonds and C-H⋯O contacts form R(1) (2)(6) rings and link mol-ecules into chains along b. Additional C-H⋯O contacts generate inversion dimers, with R(2) (2)(8) ring motifs, and form sheets parallel to (-102) which are linked by C-H⋯π interactions.
