[Al7{N(SiMe3)2}6]−: A First Step towards Aluminum Metal Formation by Disproportionation |

| Authors: | Andreas Purath Ralf Kppe Hansgeorg Schnckel |
| Abstract: | A “naked” aluminum atom links two aluminum tetrahedra in the Al7{N(SiMe3)2}6]− ion (see picture), which results from the reaction of a metastable AlCl solution with LiN(SiMe3)2 and crystallizes with Li(OEt2)3]+ as cation. This unique structure among molecular metal atom clusters represents a small but characteristic section of cubic close-packed aluminum. |
