尺寸很重要：而重碱金属K和Rb的孪晶双（amidophosphorano）甲烷二化物配合物是相对稳定的，Cs，最大和最正电的碱金属，分解形成一个环状产物，其与苄基铯共结晶。
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.
