Molecular clusters with archimedean and platonic shape , which in order to build a closed polyhedron, spontaneously eliminate H 2 or voluntarily encapsulate Li 2 O as a “cluster nucleus”, result from the dilithiation of primary silylphosphanes and silylarsanes with BuLi. Thus, the first mixed‐valent, decameric P 10 Li 16 cluster 1 was obtained from i Pr 3 SiPH 2 and t BuLi (molar ratio 1:2) with strict exclusion of LiOH and Li 2 O, whereas partial metalation in the presence of LiOH initially leads to a dodecameric, Li 2 O‐containing cluster 2 , from which the three‐shell cluster 3 with a [Li 6 O] 4+ core is obtained.
