Abstract
The enthalpies of combustion of the following tris-(acetylacetonato) derivatives have been measured and the standard enthalpies of formation at 298.15 K derived. –ΔH° c/kJ mol–1–ΔH° f/kJ mol–1 Al(C5H7O2)3(c) 7948.4 ± 1.1 1793.3 ± 2.0, Ga(C5H7O2)3(c) 7963.0 ± 3.6 1476.0 ± 4.5, In(C5H7O2)3(c) 7961.1 ± 2.8 1405.7 ± 3.6. The mean metal—oxygen bond enthalpy contributions in these compounds have been assessed: text-decoration:overline D(Al—O) 215.6, text-decoration:overline D(Ga—O) 156.0, and text-decoration:overline D(In—O) 136.6 kJ mol–1, and are in the expected sequence.Keywords
