The reaction of [(Cp'''Co)₂(μ,η^2:2-As₂)₂] with the decamethylsamarocenes [Cp*₂Sm(THF)₂] or [Cp*₂Sm], or the bis(tetramethyl-n-propyl)samarocene [(C₅Me₄(n-propyl))₂Sm] resulted in the mixed d/f polyarsenides [(Cp'''Co)₂As₄Sm(η⁵-C₅Me₄R)₂] (R=Me, n-propyl). They are the first structural representatives of open chain-like polyarsenides as ligands in the coordination sphere of lanthanides. Their formation can be explained by an intramolecular As-As coupling within the cobalt polyarsenide complex after reduction by the divalent samarium complex. Density functional theory calculations give insight into the structural change of the (As₂)₂ unit in [(Cp'''Co(μ,η^2:2-As₂))₂] upon reduction.
