Quantity	Value	Units	Method	Reference	Comment
Δ_rH°	37.7 ± 4.1	kcal/mol	ES/EChem	Pugh and Meyer T.J., 1992	solvent: Acetonitrile; The value relies on the reaction Gibbs energy, 28.1 ± 4.0 kcal/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
Δ_rH°	>24.90	kcal/mol	ES/EChem	Pugh and Meyer, 1988	solvent: Acetonitrile; The lower limit is the reaction Gibbs energy
Δ_rH°	38.0 ± 5.0	kcal/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 12.8 ± 1.2 kcal/mol. This value, together with several estimates and auxiliary data led to the reaction enthalpy for the cleavage of Mn-Mn bond
Δ_rH°	>36.8	kcal/mol	KinS	Hopgood and Poë, 1966	solvent: Decalin; Please also see Poë, 1981. The reaction enthalpy was derived from the enthalpy of activation, 36.76 ± 0.38 kcal/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.
