  Palladium(II) complexes of 2-acylpyridines. The crystal structure of dibromo bis(phenyl-2-pyridyl ketone)palladium(II)

  摘要：

  Reaction of Pd(II) with 2-pyridine-carboxaldehyde (PC), methyl 2-pyridyl ketone (MPK) and phenyl 2-pyridyl ketone (PPK) in methanolic solutions gave six new complexes which have been characterized by elemental analysis, conductivity measurements, and IR and UV-Vis spectroscopic techniques. The ligands PC and PPK behave as monodentate and exhibit nitrogen coordination while MPK exhibits N, O ligation through the ring nitrogen and carbonylic oxygen atom in the production of a five membered chelate ring. The crystal structure of the Pd(II) complex of PPK has been determined by single crystal X-ray diffraction methods. Crystal data are: monoclinic space group P2(1)/n, a = 8.707(3), b = 14.394(3), c = 8.967(3) angstrom, beta = 93.45(2)-degrees, D(calc) = 1.871 g cm-3, V = 1121.8 angstrom 3, R(F) = 0.062; R(W) = 0.068, GOF = 2.0. The complex molecule is the trans-isomer of a square planar structure and the central Pd(II) lies on a center of symmetry and is coordinated by two bromides and two pyridine ring nitrogen atoms.
