By treating cis-[M(C6X5)2(thf)2] (M = Pd or Pt, X = F or Cl, thf = tetrahydrofuran) with [M′X′4]2- or [M′2(μ-X′)2X′4] 2- (M′ = Pd or Pt; X′ = Cl or Br) in a 2:1 ratio tri- or tetra-nuclear, homo- or heterometallic complexes of the types [NBu4]2[(C6X5) 2M(μ-X′)2M′ (μ-X′)2M(C6X5)2] or [NBu4]2[(C6X5) 2M(μ-X′)2M′(μ-X′) 2M′(μ-X′)2M(C6X 5)2] can be obtained. The molecular structure of the trinuclear anion with M = M′ = Pt, X = F, X′ = Cl has been established by single-crystal X-ray crystallography. The anion is centrosymmetric, showing a square-planar PtCl4 central unit embraced by two Pt(C6F5)2 terminal moieties bonded to the central platinum atom through double chloride bridges.
