Abstract

In the title compound (systematic name: 1,3-diiodo-4-meth­oxy-2-nitro­benzene), C7H5I2NO3, the dihedral angle between the benzene ring and the nitro group is 88.0 (3)°, and the methyl group lies almost in the same plane as the ring [deviation = 0.034 (6) Å]. In the crystal, aromatic π–π stacking occurs between inversion-related rings [centroid–centroid separation = 3.865 (3) Å and slippage = 0.642 Å]. A possible weak C—I⋯π inter­action occurs [I⋯π = 3.701 (2) Å and C—I⋯π = 130.18 (13)°], but there are no significant inter­molecular I⋯I contacts.
