Abstract

(Figure Presented) Breaking up: The first triple-decker sandwich anion [(η⁵-Cp)Li(η⁵-Cp)Li(η⁵-Cp)] ^_ of lithocene (Cp = C₅H₅) (observed in the charge-separated complex [(L)Li(μ-Cp)Li-(μ-Cp)Li(L)]⁺[(η ⁵-Cp)Li(η⁵-Cp)Li(η⁵-Cp)]^-) is formed in the reaction of [Cp₂V] with hppLi (hppH = 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2-a]pyrimidine). The V≡V-bonded complex [V₂(hpp)₄] (L) effectively acts as a ligand to intercept the polymeric structure of [CpLi]_∞ (see scheme).
