Aluminum subhalides of the type Al₂₂X₂₀·12L (X = Cl, Br; L = THF, THP) are the only knownrepresentatives of polyhedral aluminum subhalides and exhibit interesting multicenter bonding properties. Herein,we report on the synthesis and structural investigation of the first chlorides of this type. Additional investigationsapplying solid-state ²⁷Al NMR (MAS), XPS (of Al₄Cp*₄ and Al₂₂X₂₀·12L), and quantum chemical calculationsshed more light upon the structure of the molecules and possible Al modifications.
