Using an accurate transpiration method, AlF was sublimed near 1200 K into argon containing 0, 0.02, and 0.76 atm of HF, but no reaction between AlF and the HF was detected within the precision (about 1%). Two alternative structures of HAlF are postulated. An upper bound for extent of reaction corresponds to > - 33 kcal (- 138 kJ) for AlF (g) + HF (g) = HAlF (g); this indicates a far lower stability of HAlF (g) than that of LiAlF (g) or NaAlF (g) when formed similarly.
