In the title compound, C12H11IO4, the C and O atoms of both methoxy groups lie very close to the mean plane of the six C atoms of the benzene ring. The O and C atoms of the group lying closest to the I atom are 0.012 (3) and 0.022 (4) Å, respectively, out of the mean plane. For the other methoxy group, the corresponding distances are 0.020 (3) and 0.078 (4) Å. In the crystal, there are only very weak intermolecular C—H...O hydrogen bonds and O...I contacts [3.080 (2) Å]. The molecules are approximately parallel to (100), forming a layered structure.
