1,1′,2,2′-Tetramethyl-3,3′-(p-phenylenedimethylene)diimidazol-1-ium bis(trifluoromethanesulfonate)

Abstract

In the solid form of the title imidazolium-based ionic liquid salt, C18H24N42+·2CF3SO3−, the complete cation is generated by a crystallographic inversion centre. The five-membered imidazole ring is approximately perpendicular to the six-membered phenylene ring [dihedral angle = 85.11 (11)°]. In the crystal, the components are linked by C—H...O interactions.
