Line them up! Crystalline, polymeric arrays of heterotrimetallic (Li 4 Na 2 K 2 ) tert ‐butoxides of definite composition have been obtained by mixing the individual Li, Na, and K alkoxides. In the crystal, [Li 4 Na 2 K 2 (μ 3 ‐O t Bu) 6 (μ 4 ‐O t Bu) 2 ] units (see picture: Li blue, Na green, K purple, C white, O red) are joined through their terminal K ions by η 6 :η 6 ‐C 6 H 6 or N , N ′‐tetramethylethylenediamine bridges.
