anion [P(C2F5)3F2H]–. The compound [PPh4][P(C2F5)3F2H] is obtained as a colorless solid on a multigram scale by salt metathesis in aqueous THF. Combining [P(C2F5)3F2H]– with various imidazolium and pyridinium cations affords ionic liquids with melting points well below room temperature. (C2F5)3PF2 also abstracts hydrides from amines, affording the hydridophosphate anion [P(C2F5)3F2H]– and the corresponding
