摘要：

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. © 2009 Wiley-VCH Verlag GmbH & Co.
