The title compound, C

H
22
N
4
S
2
, was obtained by the reaction of sulfur with the corresponding quaternary salt in the presence of K
2
CO
3
. It crystallizes with two half-molecules in the asymmetric unit; the complete molecules are generated by inversion symmetry with the central CH
2
—CH
2
bonds of the hexane bridges being located on inversion centres. In each molecule, the C
6
-alkyl chain adopts a typical antiperiplanar conformation and the two heterocyclic rings are oriented antiparallel to each other. In the crystal, molecules are linked by C—H...π interactions, forming layers lying parallel to the
ac
plane.
