Salts of the tetrakis(pentafluoroethyl)aluminate anion [Al(C F ) ] were obtained from AlCl and LiC F . They were isolated with different counter-cations and characterized by NMR and vibrational spectroscopy and mass spectrometry. Degradation of the [Al(C F ) ] ion was found to proceed via 1,2-fluorine shifts and stepwise loss of CF(CF ) under formation of [(C F ) AlF ] (n=1-4) as assessed by NMR spectroscopy and mass spectrometry and supported by results of DFT calculations. In addition, the [(C F )AlF ] ion was structurally characterized.
