Description:
AbstractThe reaction of [(Cp′′′Co)2(μ,η2:2‐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,η2:2‐As2)}2] upon reduction.
