title: 4,7,8-Trimethyl-2H-chromen-2-one.
abstract: The mol-ecule of the title compound, C(12)H(12)O(2), is essentially planar, with a maximum deviation from the mean plane of all non-H atoms of 0.038 (1) Å for the methyl C atom in the 8-position. The crystal structure is characterized by anti-parallel π-π stacking along the c axis, with centroid-centroid distances as short as 3.866 (1) Å. In the crystal, C-H⋯O hydrogen bonds connect the mol-ecules across the stacks into ribbons in the a-axis direction.
