Action of HCl upon the Pt-C bonds in 2 and 2: synthesis of tris(pentachlorophenyl), and dichloro-monopentachlorophenyl-platinate(II), , complexes

The reaction of HCl on (NBu4)2 or (NBu4)2 can be interrupted after the elimination of one C6Cl5 ligand in the presence of one molar proportion of a neutral ligand L, to give (NBu4) or, (NBu4), respectively.When L is tetrahydrothiophene, it can be displaced by other neutral ligands, and this is of special value in the case of readily protonated ligands.When bidentate ligands (L-L=dppe, 4,4'-bipy) are used, the products are binuclear complexes.Finally, (NBu4) (X=F, Cl) can be obtained by a ligand rearrangement reaction between (NBu4)2 and cis-Pt(C6X5)2(CO)2.

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 .

Synthesis and Reactivity of Trinuclear Complexes of Platinum containing the Single Bridging Ligand SC4H8. Molecular Structure of 2

Trinuclear complexes of the type 2 (X = Cl, Br, I, or C6F5; SC4H8 = tetrahydrothiophene) (1)-(4) have been prepared from trans- and NBu4 (molar ratio 1:2).The SC4H8 ligands act as the single bridge between the central platinum atom and the two terminal ones.Attempts to prepare similar trinuclear complexes with singly bridging halide ligands failed since the reaction between trans- (py = pyridine) and NBu4 (molar ratio 1:2) does not take place, while trans- or (cod = cyclo-octa-1,5-diene), under similar conditions, yield cis- and 2 or and 2 respectively.The trinuclear derivatives (1) and (3) react with neutral ligands L to give different mononuclear complexes, depending on the ligand L: when L = PPh3, NBu4 and cis-; when L = CO, NBu4 and trans-.The molecular stucture of 2 has been established by a single-crystal X-ray diffraction study.The compound forms triclinic crystals in the space group P1/, with Z = 1 and unit-cell dimensions a = 12.463(3), b = 12.487(3), c = 15.137(3) Angstroem, α = 85.68(15), β = 66.04(2), and γ = 87.04(1) degree.The structure was refined to R = 0.048 and R' = 0.048.The central platinum atom in the trinuclear anion (2-) lies on a crystallographic centre of symmetry and is bonded to two Cl atoms and two S atoms (from two SC4H8 ligands), the latter acting as bridging ligands between the central and the terminal Pt atoms.

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) ...

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.
