In the title mol-ecule, C(10)H(12)N(4)O, the tetra-zole and benzene rings form a dihedral angle of 67.52 (2)°. In the crystal, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into chains along the a axis. The relatively short distance of 3.760 (3) Å between the centroids of the tetra-zole rings suggests the existence of π-π inter-actions.
