  Binuclear palladium(II), platinum(II) and platinum(IV) complexes containing 1,2-bis (diphenylphosphino)acetylene: different orientations of the diphosphine-bridges due to metal-phosphorus dπ-dπ back bonding

  摘要：

  Several novel Pd(II), Pt(II) and Pt(IV) dimers containing 1,2-bis(diphenylphosphino)acetylene (dppa) as bridging ligand have been prepared and characterized by X-ray diffraction methods, NMR spectroscopy (Pt-195{H-1}, P-31{H-1}, IR spectroscopy, elemental analyses and melting points. The X-ray structures of the former reported complexes [Pd2Cl4(dppa)(2)] (1) and [Pt2Cl4(dppa)(2)] (2) are given for the first time: 1: monoclinic, P2(1)/n, a=14.401(3), b=12.100(2), c=15.880(3) Angstrom, beta=91.36(3)degrees, Z=2, R=0.039 for 6432 observed reflections (I>3 sigma(I)); 2: orthorhombic, Pbcn, a=13.995(3), b=17.669(4), c=21.960(4) Angstrom, Z=4, R=0.052 for 2332 observed reflections (I>3 sigma(I)). These two X-ray structures are discussed with respect to the farmer given ambiguous interpretation of the X-ray structure of [PtPdCl4(dppa)(2)]. Replacement of the chlorides in 1 or 2 by iodides leads to [Pd2I4(dppa)(2)] (3) or [Pt2I4(dppa)(2)] (4). 4 is also fully characterized by an X-ray structure analysis for the first time: 4: monoclinic, P2(1)/c, a=10.586(2), b=30.526(6), c=18.383(4) Angstrom, beta=100.09(3)degrees, Z=4, R=0.061 for 4698 observed reflections (I>3 sigma(I)).The X-ray structures of 1, 2 and 4 reveal different orientations of the dppa bridges due to metal-phosphorus d pi-d pi back bonding leading to different angles between the square-planar coordination units, respectively. Replacement of the chlorides in 1 by NO2- leads to [Pd-2(NO2)(4)(dppa)(2)] (5), whereas in 2 only one chloride can be substituted by NO2- and [Pt2Cl3(NO2)(dppa)(2)] (6) is formed. A similar reaction of 2 with 2,2'-bipyridine (bipy) produces [Pt2Cl2(dppa)(2)(bipy)](BF4)(2) (7). Oxidation of 2 by chlorine gives the Pt(IV) dimer [Pt2Cl8(dppa)(2)] (8). An equimolar amount of PdCl2 reacts with one triple bond of 2 leading to [Pt2PdCl6(dppa)(2)] (9). In an analogous manner [Pd4Cl8(dppa)(2)] (10) is formed from 1 and two equimolar amounts of PdCl2. The stability and reactivity of complexes 1-10 are discussed with respect to the X-ray structures of 1, 2, 4 and [PtPdCl4(dppa)(2)].

  spectroscopy. X-Ray crystal structure analyses for complexes 3 and 4 revealed that C1C2C4C3 is twisted in two ways with a torsion angle of 21.6–30.7° for 3a, 3b, 4a and 4b and about 42° for 3c and 4c, and that their crystals are racemic mixtures. Due to the more electronegative chloride atoms in the ligand, complexes 3c and 4c show higher ν(M–S) vibrational frequencies in their Raman spectra, smaller spin–spin

  The reaction of PtCl2L (L = diphosphine) with the appropriate diphosphine L′ in ethanol followed by reduction with aqueous sodium borohydride leads to either disproportionation to give mixtures of the bis(diphosphine) complexes PtL2 and PtL′2 or to the formation of the mixed ligand complex PtLL′ depending on the diphosphines. Mixed ligand complexes are obtained when L=Ph2P(CH2)2PPh2, L′ = Ph2P(CH2PPh2cis-Ph2PCH

  crystal X‐ray structure analyses of 2 and 5 proved that the intramolecular photochemical reaction occurred. Cyanolysis of 5 gave 7, which was oxidized to dppbdO4 (8). Compounds 7, 8, and the PdII dimer complex [Pd2Cl4(dppbd)] (9) were characterized in the solid state by a single‐crystal X‐ray structure analysis. Interesting photophysial properties emerged from the UV/Vis spectra acquired for 7 and the dimer
