Abstract

In the title compound, C6H5IN2O2, 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.
