An acyclic aluminyl anion
The potassium aluminyl complex K 2 [Al{N(Dipp)SiMe 3 } 2 ] 2 was synthesised via reduction of [AlI{N(Dipp)SiMe 3 } 2 ] (Dipp = 2,6-i-Pr 2 C 6 H 3 ). This represents the first example of an aluminyl anion supported by an acyclic ligand framework. Attempts to yield the same structure with a larger lig...
