Abstract
In the title compound, C(11)H(8)O(3), the benzopyran-4-one or chromone ring system is almost planar, with a maximum deviation of 0.045 (2) Å. The crystal structure is stablized by π-π inter-actions between the benzene and pyran rings of inversion-related mol-ecules stacked along the b axis, with a centroid-centroid distance of 3.5463 (12) Å
