| Quantity | Value | Units | Method | Reference | Comment |
|---|---|---|---|---|---|
| ΔfH°solid | -349.19 ± 0.65 | kcal/mol | Review | Martinho Simões | The enthalpy of formation, quoted from Tel'noi and Rabinovich, 1977, is probably a correction of the one given in the original reference, -888.29 kcal/mol Tel'noi, Rabinovich, et al., 1972, which leads to -339.20 kcal/mol for the enthalpy of formation of Ta(OMe)5(cr) |
