Crystal structure of 6-bromo-7-fluoro-4-oxo-4H-chromene-3-carbaldehyde
In the title compound, C10H4BrFO3, a brominated and fluorinated 3-formyl-chromone derivative, all atoms are essentially coplanar (r.m.s. deviation of 0.025 Å for the non-H atoms), with the largest deviation from the least-squares plane [0.050 (6) Å] being for a benzene-ring C atom. In the crystal, mol-ecules are linked through stacking inter-actions [centroid-centroid distance between the benze...

In the title compound, C10H5BrO3, a brominated 3-formyl-chromone derivative, all atoms are essentially coplanar (r.m.s. = 0.0631 Å for the non-H atoms), with the largest deviation from the least-squares plane [0.215 (3) Å] being for the formyl O atom. In the crystal, mol-ecules are linked into tapes through C-H⋯O hydrogen bonds and these tapes are assembled by stacking inter-actions [centroid-c...

In the title compound, C10H5IO3, an iodinated 3-formyl-chromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0344 Å), with the largest deviation from the least-squares plane [0.101 (3) Å] being found for the formyl O atom. In the crystal, mol-ecules are linked through stacking inter-actions [centroid-centroid distance between the benzene rings = 3.700 (3) Å] and C-...
