title: Hydrogen bonding in substituted nitroanilines: hydrogen-bonded sheets in 4-iodo-3-nitroaniline.
abstract: In the title compound, C(6)H(5)IN(2)O(2), the nitro group is disordered over two sets of sites, each with 0.5 occupancy, and the amino N atom is pyramidal. The molecules are linked into sheets by a combination of three-centre N-H...(O)(2) hydrogen bonds involving alternative pairs of O-atom sites and two-centre N-H...N hydrogen bonds involving the pyramidal amino group.
