The Archetypal Homoleptic Lanthanide Quadruple-Decker-Synthesis, Mechanistic Studies, and Quantum Chemical Investigations.

ABSTRACT: Reduction of [Sm^III (COT^1,4-SiiPr3 )(BH₄ )(thf)] (COT^1,4-SiiPr3 =1,4-(ⁱ Pr₃ Si)₃ C₈ H₆ ) with KC₈ resulted in [Sm^III/II/III (COT^1,4-SiiPr3 )₄ ], the first example of a homoleptic lanthanide quadruple-decker. As indicated by an analysis of the bond metrics in the solid-state, the inner Sm ion is present in the divalent oxidation state, while the outer ones are trivalent. This observation could be confirmed by quantum chemical calculations. Mechanistic studies revealed not only insight into possible formation pathways of [Sm^III/II/III (COT^1,4-SiiPr3 )₄ ] but also resulted in the transformation to other mixed metal sand
