1,3-diiodo-4-meth-oxy-2-nitro-benzene), C(7)H(5)I(2)NO(3), 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 inter-action occurs [I⋯π = 3.701 (2) Å and C-I⋯π = 130.18 (13)°], but there are no significant inter-molecular I⋯I contacts.
