Evidence that liquid clathrate formation is a general phenomena in mixtures of ionic liquids with aromatic hydrocarbons is given: ionic liquids containing 1-alkyl-3-methylimidazolium cations and hexafluorophosphate, bis (trifyl) imide, tetrafluoroborate, and chloride anions form liquid clathrates when mixed with aromatic hydrocarbons. In the system 1,3-dimethylimidazolim hexafluorophosphate/benzene, the aromatic solute could be trapped in the solid state forming a crystalline 2:1 inclusion compound.
