ABSTRACT:

The investigation of the tetrahedral Al₄Cp*₄ cluster with Fourier transform ion cyclotron resonance (FT- ICR) mass spectrometry using laser desorption ionization (LDI) as the ionization method results in a couple of aluminum cluster compounds AlxCp*_y+ (x > y) with up to eight aluminum atoms. MSⁿ experiments are performed in order to understand the formation and reactivity of the different species. Quantum chemical calculations of the structure and energy for all compounds identified complete this study.

Keywords: FT-ICR mass spectrometry, metalloid clusters, aluminum
