Copper-chalcogenide clusters stabilised with linear bidentate phosphine ligands 

Abstract

The bidentate phosphine ligands bis(diphenylphosphino)acetylene and 1,4-bis(diphenylphosphino)benzene have been found effectively to stabilise polynuclear copper/chalcogenide/chalcogenolate cores, acting as intramolecular bridges between copper centres. The clusters [Cu₁₆Se₄(SePh)₈(µ-1,4-Ph₂PC₆H₄PPh₂)₄] 1 and [Cu₂₅Te₆(TeBuⁿ)₁₃(µ-Ph₂PC[triple bond, length half m-dash]CPPh₂)₆] 2 and the related binuclear complexes [(BuⁿTe)Cu(µ-Ph₂PC[triple bond, length half m-dash]CPPh₂)₃Cu(TeBuⁿ)] 3 and [(PhSe)Cu(µ-Ph₂PC[triple bond, length half m-dash]CC[triple bond, length half m-dash]CPPh₂)₃Cu(SePh)] 4 have been prepared and their molecular structures determined.
