摘要：

By reaction between cis-[Pd(C6F5)2(PhCN)2] and cis-[MX2L2] in dichloromethane, the asymmetric homo- and hetero-bimetallic complexes [R2Pd(mu-X)2ML2] are formed (M = Ni, Pd or Pt; X = Cl, Br, I or SCN; R = C6F5 or C6H2F3-2,4,6; L = PEt3, PBu3, PPh2Me or C5H5N; L2 = Ph2PCH2CH2PPh2). In chloroform solution all the gem derivatives are binuclear. The crystal structure of [(C6F5)2Pd(mu-Cl)2Pt(PEt3)2] has been solved and refined to R = 0.042 for 4241 observed reflections, confirming the existence of binuclear molecules where the Pd and Pt atoms have square-planar co-ordination [Pd-Cl 2.449(2) and 2.402(2) and Pt-Cl 2.430(2) and 2.386(2) angstrom].
