In the title compound, C(8)H(7)N(5)O(2), the benzene ring makes a dihedral angle of 45.7 (2)° with the tetra-zole ring. In the crystal structure, the mol-ecules are linked into a chain running along the a axis by N-H⋯N hydrogen bonds, and the chains are linked through π-π inter-actions between the tetra-zole rings [centroid-centroid distance = 3.450 (2) Å].
