  • Title: Behavior of P-Pt and P-Pd bonds in phosphido complexes toward electrophilic fragments.
    Author: Alonso E, Forniés J, Fortuño C, Lledós A, Martín A, Nova A.
    Journal: Inorg Chem; 2009 Aug 17; 48(16):7679-90. PubMed ID: 19627113.
    Abstract:
    The reactions between the unsaturated 30-valence-electron-count [(C(6)F(5))(2)Pt(mu-PPh(2))(2)M(PPh(3))] (M = Pt, Pd) and [M'(OClO(3))PPh(3)] (M' = Ag, Au) yield the cationic trinuclear [(C(6)F(5))(2)Pt(mu-PPh(2))(2)M(PPh(3))(M'PPh(3))][ClO(4)] (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 [(C(6)F(5))(2)Pt(mu-PPh(2))(2)Pt(PPh(3))] and the cation [Ag PPh(3)](+) has been carried out on the basis of density functional theory and shows that the Ag center interacts weakly with M and P (PPh(2) ligand) atoms of the binuclear fragment.
