Methandiide complexes (R2CM2) of the heavier alkali metals (M = potassium, rubidium, cesium): reaching the limit?
Size does matter: Whereas geminal bimetallic bis(amidophosphorano)methandiide complexes of the heavy alkali metals K and Rb are relatively stable, that of Cs, the largest and most electropositive of the alkali metals, decomposes to form a cyclic product, which cocrystallizes with benzylcesium.
