The
redox-active diphosphine ligand 1,1′-bis(diphenylphosphino)ferrocene
(dppf) has been used to stabilize the copper(I) chalcogenide clusters
[Cu12(μ4-S)6(μ-dppf)4] (1), [Cu8(μ4-Se)4(μ-dppf)3] (2), [Cu4(μ4-Te)(μ4-η2-Te2)(μ-dppf)2] (3), and [Cu12(μ5-Te)4(μ8-η2-Te2)2(μ-dppf)4] (4), prepared by the reaction of the copper(I) acetate coordination
complex (dppf)CuOAc (5) with 0.5 equiv of E(SiMe3)2 (E = S, Se, Te). Single-crystal X-ray analyses
of complexes 1–4 confirm the presence
of {Cu2xEx} cores stabilized by dppf ligands on their surfaces, where the bidentate
ligands adopt bridging coordination modes. The redox chemistry of
cluster 1 was examined using cyclic voltammetry and compared
to the electrochemistry of the free ligand dppf and the corresponding
copper(I) acetate coordination complex 5. Cluster 1 shows the expected consecutive oxidations of the ferrocene
moieties, CuI centers, and phosphine of the dppf ligand.
