Abstract

The title mol­ecule, C5H4ClN3O2, possesses mirror symmetry, with all of the atoms lying in the mirror plane. There is an intra­molecular N—H⋯O hydrogen bond involving the adjacent –NO2 and –NH2 groups. A short C—H⋯O inter­action is also observed. In the crystal, adjacent mol­ecules are linked via N—H⋯Cl and N—H⋯N hydrogen bonds, forming chains propagating along [100].
