title: 1,4-Bis[(5-phenyl-1,3,4-thia-diazol-2-yl)sulfan-yl]butane.
abstract: The asymmetric unit of the title compound, C(20)H(18)N(4)S(4), contains one half-mol-ecule situated on a twofold rotation axis, in which the thia-diazole and phenyl rings are twisted by 7.2 (3)°. In the crystal, weak inter-molecular C-H⋯π inter-actions link the mol-ecules into layers parallel to (103).
