2-({4-[(1H-Imidazol-2-ylsulfanyl)methyl]-2,5-dimethylbenzyl}sulfanyl)-1H-imidazole

The title compound, C(16)H(18)N(4)S(2), was prepared by the substitution reaction of two equivalents of 2-mercaptoimidazole for every bromine substituent of 1,4-bis­(bromo­meth­yl)-2,5-dimethyl­benzene. The mol­ecule is located on a crystallographic centre of inversion and therefore adopts a trans configuration with regards to the orientation of the two sulfur atoms. An inter­molecular N—H⋯N hydrogen bond forms layers of mol­ecules parallel to ([Image: see text]03). The dihedral angle between the central and terminal rings is 174.8 (2)°.
