The title compound, C(9)H(7)N(5), is non-planar with a dihedral angle between the substituted benzene and tetra-zole rings of 71.13 (9)°. Molecules are connected in centrosymmetric dimers by weak C-H⋯N inter-actions [C⋯N is 3.548 (5) Å]; these are the only interactions of significance in the crystal structure.
