Crystal structure of 2-bromo-4,6-dinitroaniline

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 interactions [3.5024 (12) Å] link adjacent molecules, forming a three-dimensional network. A close O...Br contact [3.259 (2) Å] may also add additional stability.
