چکیده
In the title compound, C(16)H(15)IO(4)S, the dihedral angle between the thio-phene and benzene rings is 11.50 (2)°. The methoxy O atoms deviate by 0.0060 (2), -0.1319 (2) and 0.0426 (2) Å from the phenyl ring plane. The crystal packing features C-H⋯O hydrogen bonds, which link the molecules into C(11) chains propagating in [100xxx].
