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

Abstract

The title compound, C 18 H 28 N 2 S 2 ÁCHCl 3 , 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-HÁ Á ÁS 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-HÁ Á Á(S,S) hydrogen bonds.
