| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔfH°gas | -1710. ± 7.9 | kJ/mol | Ther | Veljkovic, Neskovic, et al., 1991 | Fluoride Affinity: 37.5 kcal/mol less than AlF3; value altered from reference due to conversion from electron convention to ion convention |
| ΔfH°gas | -1773. ± 26. | kJ/mol | Latt | Mallouk, Rosenthal, et al., 1984 | Fluoride affinities from this method appear to be consistently about 10 kcal/mol too bound |
| ΔfH°gas | -1773. ± 21. | kJ/mol | Latt | Krivtsov, Titova, et al., 1977 | Halide affinities from this reference are too high. G3MP2B3 calculations indicate an dHaff ca. 46 kcal/mol; value altered from reference due to conversion from electron convention to ion convention |
| ΔfH°gas | <-1811.7 | kJ/mol | TDEq | Srivastava, Uy, et al., 1974 | BF3 + BF2- <=> BF4- + BF |
| ΔfH°gas | <-1368.2 | kJ/mol | IMRB | Stockdale, Nelson, et al., 1972 | Fluoride Affinity: > SF5 |
