  Behavior of P−Pt and P−Pd Bonds in Phosphido Complexes toward Electrophilic Fragments

  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.

  Tetranuclear Platinum Phosphido Complexes with Different Structures

  摘要：

  The addition of [NBU4]Br or [NBU4][BH4] to solutions of [Pt-4(mu-PPh2)(4)(C6F5)(4)(CO)(2)] (3) yields the complexes [NBU4](2)[Pt-4(mu-PPh2)(4)(u-X)(2)(C6F5)(4)] (X = Br, 4; H, 5) in which the two CO groups have been replaced by two anionic, bridging X ligands. The total valence electron counts are 64 and 60, respectively; thus, complex 4 does not require Pt-Pt bonds, while two metal-metal bonds are present in 5, as their NMR spectra confirm. Also, the NMR spectra indicate a nonsymmetrical "Pt(mu-PPh2)(2)Pt(mu-PPh2)(mu-X)Pt(mu-PPh2)(mu-X)Pt" disposition for 4 and 5. Treatment of 5 with HX (X = Cl, Br) yields the complexes [NBU4](2)[Pt-4(mu-PPh2)(4)(mu-H)(2)(C6F5)(3)X] (X = Cl, 6; Br, 7). These complexes react with [Ag(OClO3)PPh3] with displacement of the halide and formation of [NBU4][Pt-4(mu-PPh2)(4)(u-H)(2)(C6F5)(3)PPh3] (8). Complexes 6-8 maintain the same basic skeleton as 5, with two Pt-Pt bonds. Complex 4 is, however, an isomer of the symmetric [NBU4](2)[{(C6F5)(2)Pt(mu-PPh2)(2)Pt(mu-Br)}(2)] (9), which has been prepared by a metathetical process from the well-known [NBU4](2)[{(C6F5)(2)Pt(mu-PPh2)(2)Pt(mu-Cl)}(2)] (1). The comparison of the X-ray structures of 4 and 9 confirms the different disposition of the bridging ligands, and their main structural differences seem to be related to the size of Br- and its position in the skeleton.

A study of the electrochemical behavior of these complexes is reported. The chemical oxidation of the homonuclear platinum derivative involving two electrons yields the complex [(C6F5)2Pt(μ-PPh2)2Pt(μ-PPh2)2Pt(C6F5)2] (6), which contains Pt in average
