Crystal structure of 8-bromo-4-oxo-4H-chromene-3-carbaldehyde
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, 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, C10H5ClO3, a chlorinated 3-formyl-chromone derivative, all atoms are essentially coplanar (r.m.s. deviation = 0.032 Å for the non-H atoms), with the largest deviation from the least-squares plane [0.0598 (14) Å] being for a pyran-ring C atom. In the crystal, mol-ecules are linked through stacking inter-actions along the b axis [shortest centroid-centroid distance between ...
متن کامل6-Chloro-8-nitro-4-oxo-4H-chromene-3-carbaldehyde
In the title compound, C10H4ClNO5, the non-H atoms of the 6-chloro-chromone unit are coplanar (r.m.s. deviation = 0.017 Å) with the largest deviation from the mean plane [0.031 (2) Å] being found for the C=O C atom. The nitro group (NO2) is inclined to the chromone unit mean plane by 13.3 (2) °. The formyl group is also twisted with respect to the attached ring [C-C-C-O torsion angles = 10.8 (4...
