6-Chloro-8-nitro-4-oxo-4H-chromene-3-carbaldehyde

In the title compound, C10H4ClNO5, the non-H atoms of the 6-chlorochromone 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...
