Incorporation of group 11 metal ions into a diplatinum center leading to Pt2M heterotrinuclear complexes supported by a tridentate phosphine ligand (M=Au, Ag, Cu)

Incorporation of a monovalent group 11 metal ion (Au(I), Ag(I) or CU(I)) with d10 configuration into the Pt2 core has led to the formation of heterotrimetallic Pt2M complexes. The PtCuX assembly forms a rhombic structure when CuX fragment was introduced. The reactions could help in the synthesis of other heterotrinuclear complexes. The angle of Pt...Cu-X is less than 90 degrees resulting in a short interatomic distance between the terminal Pt and X atoms.
