Heteropolymetallic compounds containing 1,1′-bis(diphenylphosphino)ferrocene (DPPF) and pyrazolate ligands: Synthesis, spectroscopic characterization and reactivity. Crystal and molecular structure of [(DPPF)Pt(az)2] [azH = pyrazole (pzH) or 3,5-dimethylpyrazole] and [(DPPF)Pt(μ-pz)2CdI2]

From the interaction between [(DPPF)Pt(az)2] [DPPF = 1,1′-bis(diphenylphosphino)ferrocene; azH = pyrazole (pzH), 3,5-dimethylpyrazole (3,5-Me2pzH) or 4-methylpyrazole (4-MepzH)] and several MX2 acceptors (M = Zn, X = Cl, Br, I or BF4; M = Cd, X = Cl, Br, I or ClO4, M = Hg, X = Cl, Br or I; M = Ba, X = I) 16 novel heteropolymetallic compounds were synthesized and characterized by IR, far-IR, 1H and 31P, and in some cases also with 113Cd, NMR spectroscopy. Heterotrinuclear adducts [(DPPF)Pt(μ-az)2MX2] were obtained when X = halide, whereas ionic heteropentanuclear complexes [{(DPPF)Pt(μ2-az)2}2M]2+[X] 22- were afforded when X is a weak nucleophile (ClO4 or BF4). Scrambling of the ligands occurred when the reaction between [(DPPF)Pt(az)2] and Cu(II)X2 salts (X = Cl or Br) was carried out in methanol, [(DPPF)PtX2] being always obtained. X-Ray crystallography confirms the mononuclear structure of [(DPPF)Pt(az)2] (azH = pyrazole or 3,5-methylpyrazole), in which the Pt atom is in a distorted cis square planar coordination with the two cyclopentadienyl rings in a staggered conformation. In the heterotrinuclear [(DPPF)Pt(μ-pz)2CdI2], the cadmium atom is strongly distorted tetrahedral, coordinated by two N-atoms of pyrazolate rings and two iodine atoms.

1,1′-Bis(diphenylphosphino)ferrocene complexes of platinum(II) and platinum(I). Crystal and molecular structure of [(L-L)Pt(μ-H)(μ-CO)Pt(L-L)][BF4]·0.5H2O, where L-L = Fe(η5-C5H4PPh2)2

A series of platinum(II) derivatives with 1,1′-bis(diphenylphosphino)ferrocene (L-L) were synthesized and characterized in solution mainly by 1H and 31P{1H} NMR spectroscopy. The series includes, besides the known Pt(L-L)Cl2 (1), the mononuclear species Pt(L-L)(pz)2 (2, pzH = pyrazole), Pt(L-L)(3,5-Me2pz) (3, 3,5-Me2pzH = 3,5-dimethylpyrazole), [Pt(L-L)(3,5-Me2pzH)2][BF4]2 (4), and [Pt(L-L)(H2O)2][BF4]2·xH 2O (5) as well as the dinuclear species [(L-L)Pt(μ-OH)2Pt(L-L)][BF4]2 (6) and [Pt2(L-L)2H3][BF4] (7). Reaction of the hydrido complex 7 with CO (room temperature, 1 atm) gave [(L-L)Pt(μ-H)(μ-CO)Pt(L-L)][BF4] (8), formally a platinum(I) derivative. The molecular structure of [(L-L)Pt(μ-H)(μ-CO)Pt(L-L)][BF4]·0.5H2O (8a) was determined by X-ray analysis: the complex crystallizes in the triclinic space group P1 with a = 12.411 (4) A?, b = 15.930 (5) A?, c = 16.922 (7) A?, α = 100.64 (3)°, β = 98.74 (3)°, γ = 104.34 (3)°, Z = 2, and V = 3166 (4) A?3. The structure was refined to a conventional R factor of 0.025. In the dinuclear cation, the platinum atoms have cis-square-planar coordination, which shows a significant distortion toward tetrahedral geometry with P-Pt-P angles of 103.68 (6) and 103.64 (6)°. The Pt-Pt distance is 2.790 A?.
