Abstract

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)]_nwhich are binuclear (n = 1) in CHCl₃solutions. The molecular structure of [Pt(C₆F₅)₂(μ-Br)Pd(COD)(μ-Br)Pt(C₆F₅)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) Å, b = 9.3916 (18) Å, c = 18.133 (5) Å; 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.
