3,3′-(Hexane-1,6-diyl)bis(1-vinyl-4-imidazoline-2-thione)

Abstract

The title compound, C16H22N4S2, was obtained by the reaction of sulfur with the corresponding quaternary salt in the presence of K2CO3. It crystallizes with two half-molecules in the asymmetric unit; the complete molecules are generated by inversion symmetry with the central CH2—CH2bonds of the hexane bridges being located on inversion centres. In each molecule, the C6-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 theacplane.
