|---|---|---|---|---|---|
| ΔfH°gas | -1373. ± 14. | kJ/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, -3716.6 kJ/mol Tel'noi, Rabinovich, et al., 1972, which leads to -1419.2 kJ/mol for the enthalpy of formation of Ta(OMe)5(cr) |
