Synthesis and Reactivity of Binuclear Homo- or Hetero-metallic Complexes 2 (M=M'=Pd or Pt; M=Pt, M'=Pd) with Bridging Pentafluorophenyl Groups

By reacting 2 with cis- (M=Pd or Pt; thf=tetrahydrofuran) in CHCl3 the binuclear homo- or hetero-metallic complexes 2 (M=M'=Pd or Pt; M=PT, M'=Pd), containing bridging pentafluorophenyl groups, are obtained.Their structures have been established by 19F n.m.r. spectroscopy.The homometallic derivatives react with neutral (L) or anionic (X)- ligands yielding (M=Pd or Pt; L=PPh3, CO, or 1/2Ph2PCH2PPh2) or 2 (M=Pd or Pt; X=Br), respectively.The heterometallic complex 2 reacts with PPh3 or Ph2PCH2PPh2 giving rise to a mixture of cis- and 2, while its reaction with CO yields a mixture of and .

Full title: Synthesis, X-ray structure, and reactivity of (NBu4)2[Pt2(μ-C5F 5)2(6F5)4]·H 2O and (NBu4)[Pt2Ag(μ-C6F5) 2(C6F5)4O(C2H 5)2]. The first complexes containing bridging pentafluorophenyl groups. By reacting (NBu4)2[Pt(C6F5)3Cl] with AgClO4 (molar ratio 1:1) in CH2Cl2/diethyl ether, the binuclear complex (NBu4)2[Pt2(μ-C6F 5)2(C6F5)4] (1) is obtained. (NBu4)[Pt2Ag(μ-C6F5) 2(C6F5)4]·O(C 2H5)2 (2) can be prepared by reacting 1 with AgClO4 (molar ratio 1:1) or by treating (NBu4)2[Pt(C6F5)3Cl] with AgClO4 (molar ratio 1:2) in CH2Cl2/diethyl ether. Complex 2 reacts with neutral monodentate ligands (L) yielding (NBu4)[Pt2Ag(μ-C6F5) 2(C6F5)4L] (L = PPh3, 3; L = CNCy, 4). The structures of the binuclear platinum complex 1 and the trinuclear Pt2Ag complex 2 have been solved by single-crystal X-ray diffraction. Complex 1 contains the platinum atoms bridged by pentafluorophenyl groups (Pt-Pt distance = 2.714 (1) A?). Complex 2 contains two Pt-Ag bonds unsupported by other covalent bridges (Pt-Ag distances = 2.815 (2) and 2.804 (2) A?. The platinum atoms (Pt-Pt distance = 2.687 (1) A?) are bridged by two pentafluorophenyl groups and one silver atom.

Heterobinuclear PtAg compounds with platinum-silver bonds unsupported by covalent bridges. Molecular structure of (C6F5)3(SC4H 8)PtAgPPh3

Reaction of anionic platinum(II) derivatives (NBu4)[Pt(C6F5)3L] with O3ClOAgL′ affords the neutral heterobinuclear complexes (C6F5)3LPtAgL′ (L′ = PPh3, PEt3; L = SC4H8, PPh3, PEt3, PEtPh2, NC5H5) containing a direct Pt-Ag bond unsupported by covalent bridges. The molecular structure of a representative compound (L = SC4H8; L′ = PPh3) has been determined by a single-crystal X-ray diffraction study. The compound (C6F5)3(SC4H 8)PtAgPPh3 crystallizes in the monoclinic system, space group P21/n, with a = 14.006 (2) ?, b = 17.441 (3) ?, c = 17.407 (2) ?, β = 110.74 (1)°, V = 3977 (1) ?3, and Z = 4. The structure was refined to least-squares residuals of R = 0.0414, Rw = 0.0518, and quality of fit = 0.95. The platinum atom is in a square-pyramidal environment, with SC4H8 and the three C6F5 ligands in the square plane and the Ag-PPh3 moiety in the apical position. The Pt-Ag distance of 2.637 (1) ? is the shortest observed to date, indicating a direct Pt-Ag bond of substantial strength. The silver atom makes short contacts with o-fluorine atoms of the C6F5 groups (Ag?F(6) = 2.757 (7) ?; Ag?F(11) = 2.791 (7) ?; Ag?F(1) = 2.763 (8) ?). Acetone solutions of these complexes behave as 1:1 electrolytes because of cleavage of the Pt-Ag bond by the donor solvent. Addition of excess ligand L′ causes cleavage of the metal-metal bonds to give ionic derivatives of the type [AgL′n]+[Pt(C6F5) 3L]- (n = 2, 3).
