Crystal structure of 6,7-dichloro-4-oxo-4H-chromene-3-carbaldehyde
In the title compound, C(10)H(4)Cl(2)O(3), a dichlorinated 3-formylchromone, the non-H atoms of the 4H-chromene ring are essentially coplanar (r.m.s. = 0.0188 Å), with the largest deviation from the least-squares plane [0.043 (2) Å] being for the pyran C=O C atom. The α,β-unsaturated carbonyl O ato...
