The synthesis of Al4R4 (R = C5(CH3)4H) (3) and the tetrahedral structure in the solid state are described. These results as well as the 27Al NMR spectra of 3 in solution are in line with the data obtained from DFT calculations. These calculations also support the failed observation of a monomeric AlR species in solution. Monomeric and tetrameric molecules of 3 are discussed with respect to those of (AlCp∗)4 (1) and (AlCp)4 (2). The increasing Al–Al bond strength from 1 to 3 and 2 from X-ray data is also supported by structural and energetic results from DFT calculations.
Graphical abstractStructure and Al–Al bond energy of the second substituted Al4Cp4 compound are discussed in comparison to Al4Cp4∗ and its high stability.Figure optionsDownload full-size imageDownload as PowerPoint slide
