ΔrH° | 158. ± 17. | kJ/mol | ES/EChem | Pugh and Meyer T.J., 1992 | solvent: Acetonitrile; The value relies on the reaction Gibbs energy, 118. ± 17. kJ/mol Pugh and Meyer T.J., 1992, and an estimated value, 133.9 J/(mol K), for the reaction entropy Pugh and Meyer T.J., 1992 |
ΔrH° | >104.2 | kJ/mol | ES/EChem | Pugh and Meyer, 1988 | solvent: Acetonitrile; The lower limit is the reaction Gibbs energy |
ΔrH° | 159. ± 21. | kJ/mol | PAC | Goodman, Peters, et al., 1986 | solvent: Hexane, cyclohexane, thf or acetonitrile; The average value of the enthalpy of the reaction Mn2(CO)10(solution) = 2xMn(CO)5(solution) + (1-x)Mn2(CO)9(solution) + (1-x)CO(solution) in the solvents indicated is 53.4 ± 5.2 kJ/mol. This value, together with several estimates and auxiliary data led to the reaction enthalpy for the cleavage of Mn-Mn bond |
ΔrH° | >154. | kJ/mol | KinS | Hopgood and Poë, 1966 | solvent: Decalin; Please also see Poë, 1981. The reaction enthalpy was derived from the enthalpy of activation, 153.8 ± 1.6 kJ/mol Hopgood and Poë, 1966 Poë, 1981, by assuming a negligible barrier for the radical recombination. This procedure was later considered to yield a low limit of the reaction enthalpy Poë, 1983 Marcomini and Poë, 1984 Marcomini and Poë, 1983 Coville, Stolzenberg, et al., 1983.
