Thermochemistry of tri(tropolonato)- and tri(4-methyltropolonato)-aluminium(III)

Enthalpies of formation of tri(tropolonato)- and tri(4-methyltropolonato)-aluminium(III) have been determined at 298·15 K by solution calorimetry. The gas-phase enthalpies of formation have been calculated and from these the Al–O bond energies have been derived.
