The synthesis of dineopentylaluminum hydride, H-Al(CH2CMe 3)2, is known in the literature since 1988. We determined the crystal structure of this important starting material and found different ring sizes with dimeric versus trimeric formula units. The molecular shape depends on the polarity of the solvent used for recrystallization (n-pentane or 1,2-difluorobenzene). The synthesis of diphenylaluminum hydride, which is also long known in the literature, was optimized. It has a trimeric structure in the solid state with an Al3H3 heterocycle.
Redistribution Reactions Involving Lithium Aluminium Hydride and Lithium Tetraphenylaluminate

Redistribution reactions involving LiAlH4 and LiAlPh4 were performed by mixing the reagents in appropriate ratios.The products: LiAlH3Ph, LiAlH2Ph2 and LiAlHPh3 were isolated and characterised by elemental analysis, infrared and nmr spectroscopy and DTA-TGA analysis.These products were also prepared by the reaction of PhLi with AlHnPh3-n (where n=1-3) in diethylether.Also PhAlH2 and Ph2AlH were prepared by the reaction of Ph3Al and AlH3 in both diethyl ether and THF in the appropriate stoichiometric ratios.
