Reaction of a mixture of 1,1‐bis(cyclopentadienyl)cyclohexane and pentamethylenefulvene with metallic sodium in THF led to a mixture of cyclohexylidene‐bridged bis(cyclopentadienyl) sodium and two‐cyclohexylidene‐bridged tri(cyclopentadienyl) sodium. Reaction of the salt solutions with anhydrous YbCl3 in THF afforded a ytterbium complex mixed‐ligated by bridged bis(cyclopentadienide) and bridged tri(cyclopentadienide).
