Crystal structure of 7-bromo-4-oxo-4H-chromene-3-carbaldehyde

Crystal structure of 7-bromo-4-oxo-4H-chromene-3-carbaldehyde

In the title compound, C10H5BrO3, a brominated 3-formylchromone 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, molecules are linked into tapes t...
