Abstract

The mol-ecule of the title compound, C(6)H(7)N(3)O(2), a derivative of o-phenyl-enediamine, nearly shows non-crystallographic C(s) symmetry. C-C-C angles span the range 116.25 (11)-122.35 (11)°. In the crystal, inter-molecular N-H⋯O and N-H⋯N hydrogen bonds connect mol-ecules 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.
