Copper-chalcogenide clusters stabilised with linear bidentate phosphine ligands
摘要：
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(-1,4-Ph2PC6H4PPh2)4] 1 and [Cu25Te6(TeBun)13(-Ph2PCCPPh2)6] 2 and the related binuclear complexes [(BunTe)Cu(-Ph2PCCPPh2)3Cu(TeBun)] 3 and [(PhSe)Cu(-Ph2PCCCCPPh2)3Cu(SePh)] 4 have been prepared and their molecular structures determined.
