Abstract
Enthalpies of formation of the crystalline title complexes have been determined at 298.15 K by solution calorimetry: ΔHf [Al(tfpd)3(c)]=–892.7 ± 3.1 and ΔHf [Al(tmhd)3(c)]=–571.5 ± 3.1 kcal mol–1. Gas-phase enthalpies have been calculated, and from these the Al–O bond energies have been derived.
