Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p> The synthesis of dineopentylaluminum hydride, H‐Al(CH₂CMe₃)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 (<italic>n</italic>‐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.</p> </abstract>
