Two-electron oxidation of a triruthenium nido-ruthenacyclopentadiene complex, {Cp*Ru(μ-H)}₃(CMeCR−CHCH) (1a; R = H, 1b; R = Me, Cp* = η⁵-C₅Me₅), proceeds at −78 °C and exclusively affords a cationic closo-ruthenacyclopentadiene complex, [(Cp*Ru)₂{Cp*Ru(CHCMe−CRCH)}(μ-H)₂](PF₆) (6a; R = H, 6b; R = Me).
