A neutral cyclic aluminium (I) trimer.

ABSTRACT: As part of the quest to develop metal-based redox chemistry beyond the d-block, low oxidation state aluminium complexes have gained wide recognition as discrete and versatile 2-electron reductants. Despite reports of monomeric, dimeric and tetrameric neutral structures, as well as a range of charged aluminyl compounds, neutral trimeric structures have remained notably absent. Furthermore, trimeric nuclearity has previously not been considered when investigating reaction mechanisms. Here, we report two neutral Al^I trimers, cyclotrialumanes. The molecules are extensively characterised using both experimental and computational techniques, with the Al-Al bonds described as principally covalent in nature and the trimeric structure shown to be retained in solution. The cyclotrialumane
