  Synthesis and characterization of the novel Pt(II) complexes of the types cis- and trans-Pt(Ypy)(pyrazine)Cl2, K2[Cl3Pt(μ-pyrazine)PtCl3] and trans, trans-(Ypy)Cl2Pt(μ-pyrazine)Pt(Ypy)Cl2 (Ypy=pyridine derivative)

  摘要：

  New types of Pt(II) mixed-ligand complexes containing a pyridine derivative (Ypy) and pyrazine (pz) were synthesized. The compounds were characterized by infrared spectroscopy and by multinuclear (H-1, C-13 and Pt-195) magnetic resonance. The complexes cis-Pt(Ypy)(pz)Cl-2 were synthesized from the reaction of K[Pt(Ypy)Cl-3] with pyrazine (1:1 proportion) in water. When the reaction was carried on in a 2:1 ratio, a mixture of compounds was obtained, which was refluxed in CH2Cl2 for several days. The final product was found to be pure and it was identified as trans, trans-Cl-2(Ypy)Pt(mu-pyrazine)Pt(Ypy)Cl-2. The cis monomers isomerize to the trans isomers in organic solvents. Different methyl derivatives of pyridine were studied in order to determine the influence of substitution in ortho position on the pyridine ligand in the complexes. In IR spectroscopy, the cis monomers showed two v(Pt-Cl) bands, while the trans monomers and dinuclear species showed only one v(Pt-Cl) band. The NMR results were interpreted in relation to the solvent effect, which seems important in these complexes. The Pt-195 NMR signals of the cis monomers were found at slightly higher. fields than those of the corresponding trans isomers. The coupling constants J(Pt-195-H-1) and J(Pt-195-C-13) are larger in the cis geometry. The delta(Pt-195) of the dinuclear species were found close to those of the trans monomers and the coupling constants are similar to those of the trans monomers, strongly suggesting a trans-trans configuration for the dinuclear compounds. The pyrazine-bridged complex K-2[Cl3Pt(mu-pz)PtCl3] was also synthesized and spectroscopically studied. The crystal structures of the compounds cis-Pt(3,5-lut)(pz)Cl-2 and trans-Pt(2,4,6-col)(pz)Cl-2 were determined by X-ray diffraction methods. (C) 2008 Elsevier B.V. All rights reserved.

  signals of the cis monomers were found at slightly higher fields than those of the corresponding trans isomers. The δ ( 195 Pt) of the dimers were found close to those of the trans monomers. The NMR results were interpreted in relation to the solvent effect, which seems important in these complexes.

  摘要合成了Ypy =吡啶衍生物和pm =嘧啶的顺式和反式-Pt（Ypy）（pm）Cl 2型混合配体配合物，并通过红外光谱和多核（195 Pt，1 H和13 C ）磁共振波谱学。顺式化合物是由K [Pt（Ypy）Cl 3]与嘧啶（1：1比例）在水中反应制得的，而大多数反式异构体是由顺式化合物的异构化合成的。顺式异构体不能与邻位含有两个–CH 3基团的Ypy配体分离。当以Pt∶pm比＝ 2∶1进行K [Pt（Ypy）Cl 3]与嘧啶的水反应时，形成了嘧啶桥连的双核物质。只有最稳定的反式-反式异构体才能分离出纯净的。在红外光谱中，顺式单体显示出两个ν（Pt–Cl）谱带，反式单体和二聚体仅显示一个ν（Pt–Cl）谱带。发现顺式单体的195 Pt NMR信号的场强于相应的反式异构体的场。发现二聚体的δ（195 Pt）接近反式单体的δ。解释了NMR结果与溶剂效应的关系，这在这些配合物中似乎很重要。在顺式几何中，耦合常数J（195
