2-(4-Methyl-phen-yl)-5-[({[5-(4-methyl-phen-yl)-1,3,4-thia-diazol-2-yl]sulfan-yl}meth-yl)sulfan-yl]-1,3,4-thia-diazole.

In the title compound, C19H16N4S4, the mol­ecules exhibit a butterfly conformation, where the thia­diazole and attached benzene rings in two wings are almost coplanar, with dihedral angles of 0.8 (3) and 0.9 (3)°, respectively, while the two thia­diazole rings form a dihedral angle of 46.3 (3)°.
