PROBLEM TO BE SOLVED: To provide an ionic fluid for use in an electrochemical cell and for organic synthesis. SOLUTION: For example, like 1-ethyl-3-methylimidazolium tris (pentafluoroethyl) trifluorophosphate, the contained anion species has the following general formula: [PF x (C y F) 2y + 1-z H z) 6-x] - in the above formula, 1 ≦ x <6,1 ≦ y ≦ 8 and 0 ≦ z ≦ 2y + 1. |
