6-Methyl-4-oxo-4H-chromene-3-carbaldehyde

Abstract

In the title compound, C11H8O3, 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 interactions between the benzene and pyran rings of inversion-related molecules stacked along the b axis, with a centroid–centroid distance of 3.5463 (12) Å
