The asymmetric unit of the title compound, C(14)H(10)N(4)O(2), contains two independent mol-ecules with similar structures. In one mol-ecule, the tetra-zole ring is oriented at dihedral angles of 17.71 (16) and 57.13 (17)°, respectively, to the central benzene ring and the terminal benzene ring; in the other mol-ecule, the corresponding dihedral angles are 16.46 (18) and 75.87 (18)°. Inter-molecular N-H⋯N hydrogen bonds and weak C-H⋯O and C-H⋯N hydrogen bonds occur in the crystal structure.
