Abstract

The mol­ecules of the title compound, C₅H₅N₃O₄, are approximately planar. The nitro group makes a dihedral angle of 1.3 (4)° with the plane of the six-membered ring. This coplanar disposition is a reason for the changes in valence angles in the vicinity of the nitro group. Mol­ecules are connected into dimers by means of N—H⋯O hydrogen bonds, and these dimers make larger structures with the help of relatively short C—H⋯O hydrogen bonds.
