Bottom Line: In the title compound, C10H5IO3, an iodinated 3-formyl-chromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0259 Å), with the largest deviation from the least-squares plane [0.056 (5) Å] being found for the formyl O atom.In the crystal, mol-ecules are linked through I⋯O halogen bonds [I⋯O = 3.245 (4) Å, C-I⋯O = 165.95 (13) and C=O⋯I = 169.7 (4)°] along [101].The supra-molecular chains are assembled into layers via π-π stacking inter-actions along the b axis [shortest centroid-centroid distance between the pyran and benzene rings = 3.558 (3) Å].

ABSTRACT
In the title compound, C10H5IO3, an iodinated 3-formyl-chromone derivative, the non-H atoms are essentially coplanar (r.m.s. deviation = 0.0259 Å), with the largest deviation from the least-squares plane [0.056 (5) Å] being found for the formyl O atom. In the crystal, mol-ecules are linked through I⋯O halogen bonds [I⋯O = 3.245 (4) Å, C-I⋯O = 165.95 (13) and C=O⋯I = 169.7 (4)°] along [101]. The supra-molecular chains are assembled into layers via π-π stacking inter-actions along the b axis [shortest centroid-centroid distance between the pyran and benzene rings = 3.558 (3) Å].
