Abstract

When Al2(OtBu)6 is treated with ethanol, Al9O3(OEt)21 (1) is obtained, which is a missing link in the series of polynuclear aluminum alkoxides. Alcoholysis of Al2(OtBu)6 in 2‐propanol yields the well‐known homoleptic compound Al4(OiPr)12 (2). As recently published, similar reactions with Fe2(OtBu)6 gave different structures. However, there are recurring structural patterns from alkoxide chemistry found. For a deeper understanding of this hardly predictable chemistry, compounds have to be correlated by such common structural motifs. We briefly report the syntheses of 1 and 2 and the crystal structure of 1. In addition, we provide an improved synthetic procedure for the preparation of the precursor Al2(OtBu)6. The structure of the new compound 1 is comprehensively compared to related structures from literature.
