摘要
The reactions between the unsaturated 30-valence-electron-count [(C6F5)(2)Pt(mu-PPh2)(2)M(PPh3)] (M = Pt, Pd) and [M'(OClO3)PPh3] (M' = Ag, Au) yield the cationic trinuclear [(C6F5)(2)Pt(mu-pph(2))(2)M(PPh3)(M'PPh3)][ClO4] (M = Pt, Pd; M'=Ag, Au), which displays Pt-M and M-M' bonds. The X-ray structures of the complexes reveal that the core of the molecules is planar and the Pt-M and M-M' distances point to the presence of Pt-M and M-M' bonds. A computational study on the formation of these complexes and the analysis of the interaction between the binuclear fragment [(C6F5)(2)Pt(mu-PPh2)(2)Pt(PPh3)] and the cation [Ag PPh3](+) has been carded out on the basis of density functional theory and shows that the Ag center interacts weakly with M and P (PPh2 ligand) atoms of the binuclear fragment.
