Quantity	Value	Units	Method	Reference	Comment
Δ_fH°_gas	-27.3 ± 1.3	kcal/mol	Review	Martinho Simões	Selected data. The enthalpy of formation relies on -428.51 ± 0.45 kcal/mol for the enthalpy of formation of Al(acac)3(cr). Liquid triethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.1% Smith, 1967, so that the "real" liquid should be described as [Al(Et)3]2.
Δ_fH°_gas	-23.6 ± 1.6	kcal/mol	Review	Martinho Simões	Liquid triethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.1% Smith, 1967, so that the "real" liquid should be described as [Al(Et)3]2.
Δ_fH°_gas	-39.13 ± 0.88	kcal/mol	Review	Martinho Simões	Liquid triethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.1% Smith, 1967, so that the "real" liquid should be described as [Al(Et)3]2.
Δ_fH°_gas	-34.4 ± 2.2	kcal/mol	Review	Martinho Simões	Liquid triethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.1% Smith, 1967, so that the "real" liquid should be described as [Al(Et)3]2
Δ_fH°_gas	-23.9 ± 1.2	kcal/mol	Review	Martinho Simões	The enthalpy of formation was quoted from Tel'noi and Rabinovich, 1980 and relies on experimental data in Fic, 1966. Liquid triethylaluminum contains a very small molar fraction of monomer at 298 K, ca. 0.1% Smith, 1967, so that the "real" liquid should be described as [Al(Et)3]2.
