Dimethyl 5-amino-2,4,6-triiodo­isophthalate

The title compound, C(10)H(8)I(3)NO(4), crystallizes with two mol­ecules in the asymmetric unit. The I atoms and the benzene ring plane in the two mol­ecules are approximately coplanar, the I atoms deviating by −0.1631 (1), 0.0704 (1) and −0.0507 (1) Å from the mean plane of the benzene ring in one mol­ecule and by 0.1500 (1), −0.0034 (1) and −0.1213 (1) Å in the other. The planes of the ester groups are almost orthogonal to those of the benzene rings in both mol­ecules, forming dihedral angles of 83.5 (3), 76.4 (3), 97.3 (1) and 75.7 (1)°. The mean planes of the benzene rings in two mol­ecules are inclined at 69.8 (3)° with respect to each other. In the crystal, inter­molecular I⋯O inter­actions link the mol­ecules into infinite chains. In addition, N—H⋯O and non-classical C—H⋯O hydrogen bonds are observed.
