6-Chloro-7-methyl-4-oxo-4H-chromene-3-carbaldehyde.

Ishikawa Y - Acta Crystallogr Sect E Struct Rep Online (2014)

Bottom Line: In the title compound, C11H7ClO3, a chlorinated and methyl-ated 3-formyl-chromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0670 Å), with the largest deviation from the least-squares plane [0.2349 (17) Å] being for the pyran carbonyl O atom.In the crystal, mol-ecules are linked through π-π stacking inter-actions along the a axis [centroid-centroid distance between the pyran rings = 3.824 (6) Å] and two stacks are connected by type I halogen-halogen inter-actions between the Cl atoms [Cl⋯Cl = 3.397 (3) Å].
