Treatment of cis-[M(C6X5)2(THF)2] (M = Pd, Pt; X = F, Cl; THF = tetrahydrofuran) with M′X′2(COD) (M′ = Pd, Pt; X′ = Cl, Br, I; COD = 1,5-cyclooctadiene) results in the formation of homo- and heteronuclear palladium or platinum complexes of general formula [(C6X5)2M(μ-X′) 2M′(COD)]n which are binuclear (n = 1) in CHCl3 solutions. The molecular structure of [Pt(C6F5)2(μ-Br)Pd(COD)(μ-Br)Pt(C 6F5)2(μ-Br)-Pd(COD)(μ-Br)] has been established by single-crystal X-ray crystallography, showing that the complex is tetranuclear in the solid state. The molecule resides on a center of symmetry and can be regarded as an eight-membered ring skeleton being made up of two Pt(C6F5)2 and two Pd(η4-1,5-C8H12) groups in an alternate way connected by single bromide bridges. Crystal data: monoclinic, a = 26.742 (6) A?, b = 9.3916 (18) A?, c = 18.133 (5) A?; β = 108.424 (22)°; space group C2/c; Z = 4. The structure has been solved from diffractometer data by direct and Fourier methods and refined by full-matrix least squares to R = 0.0369 for 3059 observed reflections.
