Abstract: The title compound (PBT), C₁₄H₁₄N₄S₄, possesses C₂ symmetry, with the twofold axis bisecting the central benzene ring. The two terminal 2-(5-methyl-1,3,4-thiodiazolyl)thio groups adopt a trans conformation with respect to the benzene moiety, and the dihedral angle between the two thiodiazole planes is 61.3 (2)°, while that between the thiodiazole and benzene planes is 79.4 (5)°.
