Heterotrimetallic Salts: Synthesis, Structures, and Superbase Reactivity of Crystalline tert-Butoxides [Li4Na2K2(OtBu)8(μ-L)]n

Line them up! Crystalline, polymeric arrays of heterotrimetallic (Li4Na2K2) tert‐butoxides of definite composition have been obtained by mixing the individual Li, Na, and K alkoxides. In the crystal, [Li4Na2K2(μ3‐OtBu)6(μ4‐OtBu)2] units (see picture: Li blue, Na green, K purple, C white, O red) are...

Zusammenfassung:Line them up! Crystalline, polymeric arrays of heterotrimetallic (Li4Na2K2) tert‐butoxides of definite composition have been obtained by mixing the individual Li, Na, and K alkoxides. In the crystal, [Li4Na2K2(μ3‐OtBu)6(μ4‐OtBu)2] units (see picture: Li blue, Na green, K purple, C white, O red) are joined through their terminal K ions by η6:η6‐C6H6 or N,N′‐tetramethylethylenediamine bridges.
