3-Nitrobenzene-1,2-diamine

Abstract

The molecule of the title compound, C6H7N 3O2, a derivative of ophenylenediamine, nearly shows non-crystallographic Cs symmetry. C-C-C angles span the range 116.25 (11)-122.35 (11)°. In the crystal, intermolecular N-H⋯O and N-H⋯N hydrogen bonds connect molecules into undulating sheets perpendicular to the crystallographic a axis. A weak intra-molecular N-H⋯O hydrogen bond is also observed. No π-stacking is observed in the crystal structure.
