Lithium‐rich main group element clusters characterize the title compounds 1 and 2 (right: structure of 1 without silyl substituents; back = P,O, white = Li), which are obtained by lithiation of the appropriate primary silylphosphane and silylarsane, respectively, with two equivalents of n BuLi in the presence of Li 2 O. The frameworks of 1 and 2 are topologically best described as two interpenetrating shells of silylated P or As dianions and Li cations, with a formal charge of −4, which encapsulate a [Li 6 O] 4+ octahedron.
