ABSTRACT
The mol-ecule of the title compound, C(9)H(9)N(5)O, is essentially planar (r.m.s. deviation of all atoms = 0.02 Å) except for the NH(2) H atoms. An intra-molecular hydrazinyl-idene-carbonyl N-H⋯O=C hydrogen bond is present. In the crystal, mol-ecules are connected via N-H⋯N/O hydrogen bonds, forming thick layers parallel to (100).

Packing diagram of the title compound, viewed perpendicular to (100). Thick dashed bonds represent classical H bonds. Atom names correspond to the asymmetric unit; hydrogen bonds are numbered according to the Table on page Sup-7 (#4, the weaker part of a three-centre interaction, is omitted, as is the intramolecular interaction #5).
