A new room temperature molten salt (room temperature ionic liquid), 1-ethyl-2,3-dimethylimidazolium fluorohydrogenate (EDMIm(HF)2.3F), has been prepared by the reaction of EDMImCl and large excess of anhydrous hydrogen fluoride (aHF). EDMIm(HF)2.3F is composed of EDMIm cation and (HF)nF anions (fluorohydrogenate anions) and exhibits the conductivity of 56.9 mS cm−1 and viscosity of 6.8 cP at 298 K. Electrochemical window of EDMIm(HF)2.3F determined by cyclic voltammetry using a glassy carbon electrode as a working electrode is about 2.9 V that is close to the window of 1-ethyl-3-methylimidazolium fluorohydrogenate (EMIm(HF)2.3F) reported previously.
