Claim:
A fluoroalkyl phosphate of the formula (I) M n+ [PF x (C y F 2y+1−z H z ) 6−x ] n − (I) in which 1≦x<6, 1≦y≦8, 0≦z≦2y+1, 1≦n≦3, and M n+ is one of the following cations: NR 1 R 2 R 3 R 4 , PR 1 R 2 R 3 R 4 , P(NR 1 R 2 )(NR 3 R 4 )(NR 5 R 6 )(NR 7 R 8 ), C(NR 1 R 2 )(NR 3 R 4 )(NR 5 R 6 ), where R 1 to R 8 are H, C y F 2y+1−z H z or an aromatic radical.
