Abstract

The binuclear anionic derivatives (NBu₄)₂[(C₆F₅)₂M(μ-PPh₂)₂M′(C₆F₅)₂] (M = M′ = Pd, 1; M = M′ = Pt, 2; M = Pd, M′ = Pt, 3) have been obtained by treating either (NBu₄)₂[(C₆F₅)₂M(μ-X)₂M′(C₆F₅)₂] (X = Cl, Br) with LiPPh₂ (1,2) or [cis- M(C₆F₅)₂(PPh₂)₂]^2- with M′(C₆F₅)₂(THF)₂ (1,2,3). These binuclear derivatives react with HCl yielding the tetranuclear complexes (NBu₄)₂[(C₆F₅)₂M(μ-PPh₂)₂ M′(μ-Cl)₂M′(μ-PPh₂)₂M(C₆F₅)₂] (7: M = M′ = Pt; 8: M = M′ = Pd; 9: M = Pt, M′ = Pd). However, 2 and 3 react with HCl in the presence of PPh₃ to yield the binuclear asymmetric complexes (NBu₄)[(C₆F₅)₂M(μ-PPh₂)₂M′(C₆F₅)(PPh₃)] (10: M = M′ = Pt; 11: M = Pt, M′ = Pd). The tetranuclear complexes 7, 8, and 9 react with bidentate ligands yielding the neutral asymmetric binuclear complexes [(C₆F₅)₂M(μ-PPh₂)₂M′(LL)] (5: M = M′ = Pt; LL = dppm; 12: LL = phen; 13: M = M′ = Pd, LL = bipy). The salts Li₂[M(C₆F₅)₂(PPh₂)₂] (M = Pd, Pt) react with PtCl₂(dppm), [Pt(μ-Cl)(C₆F₅)(tht)]₂ or PtCl₂ to yield [(C₆F₅)₂M(μ-PPh₂)₂Pt-(dppm)] (4: M = Pd; 5: M = Pt), (NBu₄)[(C₆F₅)₂Pt(μ-PPh₂)₂Pt(C₆F₅)(tht)] (6) or (NBu₄)₂[(C₆F₅)₂Pt(μ-PPh₂)₂Pt(μ-Cl)₂Pt(μ-PPh₂)₂Pt(C₆F₅)₂] (7), respectively. These complexes have been characterized by IR and ¹⁹F and ³¹P NMR spectroscopy, the latter indicating that in all cases no metal-metal bonds are present. The molecular structure of [(C₆F₅)₂Pt(μ-PPh₂)₂Pt(phen)] has been established by an X-ray diffraction study. The Pt...Pt distance (3.5711(9) Å) confirms that there is no PtPt bond.
