  Synthesis and structure of rare zwitterionic complexes involving the presence of N(py)MCl3− moieties (M = Pt(II), Pd(II))

  摘要：

  The monocation 2,3-dicyano-5-[(N-methyl)-2-pyridyl}-6-(2-pyridyl)pyrazine, [(CN)(2)(2-Mepy)PyPyz](+)(1) reacts, as the iodide salt (2), under mild experimental conditions, with dichloro-di(benzonitrile)platinum (II), [(C6H5CN)(2)PtCl2], forming trans-diiodo-di(benzonitrile)platinum(II), [(C6H5CN)(2)PtI2] (3), and the complex [(CN)(2)Py(2-MePY)PyzPtCl(3)]center dot CH3CN (4), both structurally elucidated by single-crystal X-ray work. Using a parallel procedure, reaction of 2 with dichloro-di(benzonitrile)palladium(II), [(C6H5CN)(2)PdCl2], results in the formation of complex 5, [(CN)(2)Py(2-Mepy)PYzPdCl(3)]center dot CH3CN, isostructural with 4. Complex 5 is also formed by reaction of the same reactant 2 with PdCl2. Complexes 4 and 5, further characterized by IR and UV-vis spectral data, are neutral stable zwitterions presenting both a +1 pyridinium component neutralized by rare N(py)PtCl3 and N(py)PdCl3 anionic moieties, respectively (py = 2-pyridyl group). DFT calculations fit reasonably well with the observed UV-vis absorptions and provide information on the localization of the HOMO and LUMO within the species 4 and 5. (C) 2018 Elsevier B.V.

  synthesized. Evaluation of their reactivity toward different metal centers provides evidence that the dicationic fragment, otherwise reluctant to coordinate metals, readily participates in the formation of chelates when embedded into such a scaffold. Moreover, it significantly enhances the Lewis acidity of the metals to which it coordinates. This property has been used to develop a Rh catalyst that efficiently

  The cis influence of a series of anionic ligands X and Y has been evaluated through the magnitude of the Pt–P coupling constants for compounds of formula trans-[PtXY(PPh3)2]. The order of decreasing cis influence was found to be I > Cl > SePh ∼ SPh ∼ SEt > NO3 > AcO ∼ NO2 > H > Me > Ph > mtc (mtc = N,N-dimethylmonothiocarbamato-S); moreover, the cis influences of the various ligands was found to be additive. The X-ray structures of three representative compounds (t-4: X = Cl, Y = NO3; t-5: X = Cl, Y = AcO and t-12: X = Y = NO2) have also been determined.
