title: Crystal structure of 2-bromo-4,6-di-nitroaniline.
abstract: In the title compound, C6H4BrN3O4, the dihedral angles between the nitro groups and the aniline ring are 2.04 (3) and 1.18 (4)°, respectively. In the crystal, N-H⋯O and C-H⋯O hydrogen bonds and weak side-on C-Br⋯π inter-actions [3.5024 (12) Å] link adjacent mol-ecules, forming a three-dimensional network. A close O⋯Br contact [3.259 (2) Å] may also add additional stability.
