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