Abstract :
In the title compound, C11H13N3O, the seven-membered ring adopts a conformation such that the three atoms not involved in the aromatic plane lie on the same side of that plane. One hydrazinic H atom forms an intramolecular hydrogen bond to the O atom; the other forms a classical intermolecular hydrogen bond N—H⋯O, which combines with a `weak' Har⋯O interaction to build up double layers of molecules parallel to the bc plane.
