Crystal structure of 1,3-dicyclohexyl-4,5-dimethyl-1H-imidazol-3-ium-2-carbodithioate chloroform monosolvate

Abstract

The title compound, C18H28N2S2·CHCl3, crystallizes as a zwitterion. The C-S bonds are almost equivalent, with lengths of 1.666(3) and 1.657(3)Å. The S-C-S bond angle is expanded to 129.54(16)° and the N-C-N angle is reduced to the tetrahedal value of 108.8(2)°. In the crystal, adjacent molecules are linked via C-H⋯S hydrogen bonds, forming chains along [100]. The chloroform solvent molecule, which is disordered over two positions [occupancy ratio = 0.51(2):0.49(2)], is linked to the chain by bifurcated C-H⋯(S,S) hydrogen bonds.
