In the title compound, C(8)H(7)ClN(4), the phenyl and tetra-zole rings are inclined at a dihedral angle of 67.52 (6)°. In the crystal, mol-ecules are linked by an N-H⋯N hydrogen bond into a chain structure along [010]. π-π inter-actions with centroid-centroid distances of 3.526 (1) Å between adjacent tetra-zole rings further link the chains, forming a ribbon structure.
