The title compound, C10H4I2O3, is an iodinated 3-formylchromone derivative, and the atoms are essentially coplanar [r.m.s. deviation = 0.049 Å, largest deviation from the least-squares plane = 0.111 (9) Å for the CH(=O) C atom]. In the crystal, molecules are linked into a three-dimensional network through halogen bonds [I...O = 3.352 (5) and 3.405 (7) Å, C—I...O = 144.2 (3) and 154.5 (3)°, and C=O...I = 134.9 (6) and 146.0 (6)°], and π–π stacking interactions [centroid–centroid distance = 3.527 (6) Å].
