  Synthesis and Structural Analysis of the First Nanosized Platinum−Gold Carbonyl/Phosphine Cluster, Pt₁₃[Au₂(PPh₃)₂]₂(CO)₁₀(PPh₃)₄, Containing a Pt-Centered [Ph₃PAu−AuPPh₃]-Capped Icosahedral Pt₁₂ Cage

  摘要：

  The preparation and molecular structure of the initial nanosized platinum-gold carbonyl cluster, Pt-13[Au-2(PPh3)(2)](2)(CO)(10)(PPh3)(4) (1), are described. A comparative analysis reveals its pseudo-D-2h geometry, consisting of a centered Pt-13 icosahedron encapsulated by two centrosymmetrically related bidentate [Ph3PAu-AuPPh3]-capped ligands along with 4 PR3 and 10 CO ligands, to be remarkably similar to that of the previously reported Pt-17(mu(2)-CO)(4)-(CO)(8)(PEt3)(8) (2). Reformulation of 2 as Pt-13[(PtPEt3)(2)(mu(2)-CO)](2)-(CO)(10)(PEt3)(4) emphasizes the steric/electronic resemblance of the bulky-sized bidentate [Ph3PAu-AuPPh3] and [(PtPEt3)(2)(mu(2)-CO)] capping ligands in 1 and 2, respectively, as well as their identical electron counts of 162 cluster valence electrons for a centered Pt-13 icosahedron. We hypothesize that analogous steric effects of their ligand polyhedra in 1 and 2 play a crucial role along with electronic effects in the formation and stabilization of these two nanosized clusters that contain an otherwise unknown centered icosahedron of platinum atoms.

  Transformation of the cluster Pt₃(µ-CO)₃(PPh₃)₄into Pt₅(µ-CO)₅(CO)(PPh₃)₄upon impregnation onto inorganic supports

  摘要：

  将 Pt3(µ-CO)3(PPh3)4 的有机溶液浸渍到用于催化或色谱分析的无机载体上，会产生 Pt5(µ-CO)5(PPh3)4，这取决于载体的性质、预处理和所使用的溶剂；这些观察结果与簇衍生催化剂的制备有关。
