| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔfH°gas | -2171. ± 14. | kJ/mol | Ther | Aleshina, Borshchevskii, et al., 1996 | The discrepancy with Larson and McMahon, 1985 is discussed but not resolved.; value altered from reference due to conversion from electron convention to ion convention |
| ΔfH°gas | -2264. ± 35. | kJ/mol | Latt | Mallouk, Rosenthal, et al., 1984 | Fluoride affinities from this method appear to be consistently about 10 kcal/mol too bound |
