5,5'-[( p-Phenyl­enedimethyl­ene)dithio]bis­(1-phen­yl-1 H-1,2,3,4-tetra­zole).

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. [ABSTRACT FROM AUTHOR]
