Abstract:The solid‐state structures of the first rubidium and caesium pentalenides, [Rb(THF)]2[Ph4Pn] and [Cs(THF)]2[Ph4Pn] have been determined by single crystal X‐ray diffraction. Both were found to be polymeric in the solid state through interactions of the cations with the phenyl substituents, in contrast to their lighter group 1 congeners which are monomeric for lithium and sodium and THF‐bridged for potassium. Both [Rb(THF)]2[Ph4Pn] and [Cs(THF)]2[Ph4Pn] displayed increased η8 coordination, demonstrating a shif… Show more
