6,8-Diiodo-5,7-dimethoxy-4-methylcoumarin
In the title compound, C(12)H(10)I(2)O(4), the methoxy 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, molecules are linked by weak C—H⋯O hydrogen bonds and O⋯I contacts [3.194 (2) Å]....
