Abstract

In the title compound, C(12)H(10)I(2)O(4), the meth-oxy groups are twisted considerably with respect to the plane of the aromatic ring [CH(3)-O-C-C torsion angles = -85.9 (3) and -92.8 (3)°]. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds and O⋯I contacts [3.194 (2) Å].
