6-Chloro-7-fluoro-4-oxo-4H-chromene-3-carbaldehyde

In the title compound, C10H4ClFO3, a chlorinated and fluorinated 3-formylchromone derivative, all atoms are essentially coplanar (r.m.s. = 0.0336 Å for the non-H atoms), with the largest deviation from the least-squares plane [0.062 (2) Å] being for a benzene-ring C atom. In the crystal, molecules a...

description In the title compound, C10H4ClFO3, a chlorinated and fluorinated 3-formylchromone derivative, all atoms are essentially coplanar (r.m.s. = 0.0336 Å for the non-H atoms), with the largest deviation from the least-squares plane [0.062 (2) Å] being for a benzene-ring C atom. In the crystal, molecules are linked through stacking interactions [centroid–centroid distance between the benzene and pyran rings = 3.958 (3) Å and interplanar distance = 3.259 (3) Å], C—H...O hydrogen bonds, and short C...O contacts [2.879 (3) Å]. Unsymmetrical halogen–halogen interactions between the Cl and F atoms [Cl...F = 3.049 (3) Å, C—Cl...F = 148.10 (9)° and C—F...Cl = 162.06 (13)°] are also formed, giving a meandering two-dimensional network along the a axis.
