  摘要：

  In order to investigate further the chemoselectivity of reactions involving the mu-orthometalated, metal-metal bonded dinuclear Pt(I) complex [Pt-2(mu-o-C6H4PPh2)(mu-PPh2)(mu-PPh3)(2)](Pt-Pt) (1), it was reacted with HCl and HI using various stoichiometries. The first step was the breaking of the metal-carbon bond and the formation of C-H and Pt-X bonds. When a 1:1 ratio was used, the complexes [Pt2X(mu-PPh2)(PPh3)(3)] (Pt-Pt) (2, X = Cl; 3, X = I) have been obtained but the use of a 2:1 ratio resulted instead in the formation of the complexes [Pt-2(mu-H)(mu-PPh2)X-2(PPh3)(2)](Pt-Pt) (4, X = Cl; 6, X = I). The latter transformed into [Pt-2(mu-X)(mu,-PPh2)X-2(PPh3)(2)] (5, X = Cl; 7, X = I) in the presence of an additional equivalent of HX. The cis,cis- and cis,trans-isomers of 7 were also obtained by oxidation of 3 with one equivalent of iodine. Whereas compounds 4, cis,cis-5, and cis,trans-7 have been characterized in solution, the complexes 2.1/2C(7)H(8), 3, 6 and cis,cis-7 have been isolated and structurally characterized by X-ray diffraction.

  The reaction of [Co(CO)(4)](-) with [Pt2Cl(mu-PPh2)(PPh3)(3)] (1:1 ratio), which was prepared in situ by reaction of aqueous HCl with the orthometalated complex [Pt-2(mu-PPh2)(mu-o-C6H4PPh2)(PPh3)(2)], afforded the deep green triangular cluster [Pt2Co(mu-PPh2)(CO)(4)(PPh3)(2)], 7. X-ray crystallographic analysis reveals that this new cluster contains two formally monoanionic fragments, PPh2- and CO(CO)(4)(-), that bridge a d(9)-d(9) Pt(l)-Pt(l) metal-metal bond. Whereas tetracarbonylcolbaltate is generally bonded to only one metal center as a 2e donor ligand, it is best viewed here as a formally 4e donor anionic metalloligand. This model leads then to the usual 16e count for each Pt center and relates this metalloligand to other anionic bridging ligands, such as PPh2-. A comparative EHMO bonding analysis of [CO(Co)(3)L](--) (L = CO, PR3) fragments is presented which takes into account the possible coordination geometries about cobalt, trigonal bipyramidal (with C-3nu local symmetry) or edge-capped tetrahedral when referring to the ligand polyhedron (with C-2nu or C-s symmetry). The results support the description of this unusual bridging bonding mode.
