Heat of formation of tri-isopropoxyaluminium
Abstract
The heat of formation of crystalline tetramic tri-isopropoxyaluminium has been derived. ΔHt°[Al(OPrf)3]4(c)=–5149·5 kJ mol–1. From this the heat of formation of the gaseous dimer ΔHt°[Al(OPri)3]2(g)=–2446·9 kJ mol–1 has been calculated. This leads to a minimum value for the Al–O bridge bond ΔHhet=+131·5 kJ mol–1.
