The title compound, C22H18N8S2, was synthesized by the reaction of α,α′‐dibromo‐p‐xylene and 1‐phenyl‐5‐thio‐1,2,3,4‐tetrazole. In the molecule, the two tetrazole rings are almost parallel, making a dihedral angle of 9.8 (3)°. The two terminal phenyl rings attached to the tetrazole rings are perpendicular to the central benzene ring.
