【 摘 要 】

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.
