The herbicide 3-phenyl-1-(2-hydroxy-3-iodo-4,6-dimethoxyphenyl)propen-1-one, C 17 H 15 IO 4 , exists as a nearly planar molecule; the hydroxy group forms an intramolecular hydrogen bond with the carbonyl O atom.
In the title compound, C 18 H 16 O 6 , a herbicide, the dioxole ring adopts a flattened envelope conformation. The two aromatic rings at either end of the propenone linkage are almost coplanar with it. The hydroxy group is involved in an intramolecular O-HÁ Á ÁO hydrogen bond.
