摘要：

The tetranuclear complexes [NBU4](2)[(C6F5)(2)Pt(mu-PPh(2))(2)M(mu-Cl)(2)M(mu-PPh(2))(2)Pt(C6F5)(2)] (M = Pd or Pt) reacted with AgClO4 and cis-[PtCl2(PPh(3))(2)] in dichloromethane-acetone affording the neutral homo- or hetero-metallic asymmetric species [(C6F5)(2)Pt(mu-PPh(2))(2)M(mu-Cl)(2)Pt(PPh(3))(2)] 1 and 2. Treatment of their CH2Cl2 solutions with KOH in methanol rendered the corresponding mu-hydroxo derivatives 3 and 4 which reacted with HX' (X' = Cl, Br, SPh, NHC(6)H(4)Me-p or PPh(2)) to afford [(C6F5)(2)Pt(mu-PPh(2))(2)M(mu-X)(mu-X')Pt(PPh(3))(2)] (X = X' = Cl 1, 2; Br 5, 6; SPh 7. 8; X = OH, X' = NHC(6)H(4)Me-p 9, 10; X = OH, X' = PPh(2) 11, 12). The structure of 3 has been determined by single-crystal X-ray diffraction.
