  Synthesis and characterization of the iodo-bridged Pt(II) complexes {Pt(R2SO)I}2(μ-I)2 and of trans-Pt(R2SO)(pyrimidine)I2

  摘要：

  The reactions of K-2[PtI4] with sulfoxides produce the iodo-bridged dinuclear species (R2SO)IPt(mu-I)(2)Pt(R2SO)I, which have shown two resonances in Pt-195 NMR spectroscopy at average values of -4933 and -4827 ppm. The signals have been assigned to the presence of cis and trans dimeric isomers in solution. The compounds with di-n-propylsulfoxide and dibenzylsulfoxide were studied by X-ray diffraction methods and the results have shown that the two sulfoxide ligands are in trans positions. The reactions of these dimers with pyrimidine (pm) gave the compounds trans-Pt(R2SO)(pm)I-2. The Pt-195 chemical shifts of these complexes vary between -4387 and -4438 ppm. The Pt-195 coupling constants with the atoms of pyrimidine (3)J(Pt-195-H-1(2)), (3)J(Pt-195-H-1(6)) and (3)J(Pt-195-C-13(5)) are (ave.) 22, 32 and 28 Hz, respectively, suggesting a trans configuration. A few Pt-195 coupling constants with the sulfoxide atoms were observed. The (2)J vary between 56 and 71 Hz, while the (3)J are between 15 and 27 Hz. The crystal structures of the compounds with dimethylsulfoxide, di-n-propylsulfoxide and tetramethylenesulfoxide were determined, confirming the trans geometry. (C) 2002 Elsevier Science B.V.
