4-Hydroxy-3-iodo-5-methoxybenzaldehyde

Q.-L. Zhou, C.-L. Wang and Z.-L. Jing

Abstract: The title compound, C₈H₇IO₃, contains two independent molecules, each lying on a mirror plane. The two molecules differ in the orientation of the -CHO group by a 180° rotation around its bond with the benzene ring. In the mirror plane, each independent molecule is linked to a symmetry-equivalent molecule by intermolecular O-HO hydrogen bonds, forming a chain along the b axis. Short intermolecular IO contacts are observed between adjacent chains.
