摘要：
The reaction of [NBu4](2)[{(C6F5)(2)Pt(mu-PPh2)(2)Pt(mu-Cl)}(2)], A, with CO in CH2Cl2 gives the expected dinuclear compound [NBu4][(C6F5)(2)Pt(mu-PPh2)(2)PtCl(CO)], 1, which reacts with AgClO4 (1:1 molar ratio) in CH2Cl2 to produce the tetranuclear cluster [Pt-4(mu-PPh2)(4)(C6F5)(4)(CO)2], 2. The analogous complex [NBu4](2)[{(C6F5)(2)Pt(mu-PPh2)(2)Pd(mu-Cl)}(2)], B, does not react with CO under similar conditions, but treatment of B with AgClO4 (1:2 molar ratio, CH2Cl2) renders the tetranuclear compound [Pt2Pd2(mu-PPh2)(3)(C6F5)(3)(PPh2C6F5)], 3, in which the PPh2C6F5 ligand is produced through an unusual M-PPh2/M-C6F5 reductive coupling, Complex 3 reacts with CO in CH2Cl2 producing the tetranuclear complex [Pt2Pd2(mu-PPh2)(2)(mu(3)-PPh(1,2-eta(2)-Ph)-kappa(3)P)(C6F5)(3)(CO)(PPh2C6F5)], 4. The molecular structures of complexes 2 and 4 have been established by X-ray crystallography.
