  摘要：

  摘要将已知的复合反式[[Pt2I2（μ-I）2（dmso）2]] 1与2或4当量的1-甲基咪唑和4-甲基吡啶作为两个不同的N杂环配体反应。该二核结构被2和4当量的1-甲基咪唑对称裂解导致形成反式-[PtI2（1-MeIm）（dmso）]，2和反式-[PtI2（1-MeIm） 2]，4。在4-甲基吡啶的情况下，1与2和4当量的配体的反应最终终止于配合物反式[[PtI2（4-MePy）（dmso）]，3。此外，配合物2的反应性并针对一些常见的二膦配体研究了4。当配合物2和4与dppm反应时，形成通式为[PtI2（P ^ P）]的配合物5、6和7，dppe和dppp配体分别使用线性dppac配体形成双桥双膦配合物的双核配合物8和11。使用多核（1H和31P {H}）NMR光谱和元素分析对复合物进行了全面表征。通过X射线晶体学进一步确定典型配合物2的结构。此外，进行DFT计算是为了获得优化的结构，并进一步了解新配合物的吸收特性。

  The crystal structures of several Pt(II) complexes containing sulfoxide ligands are described. The two iodo bridged dimers of the type I(R(2)SO) Pt(mu-I)(2)Pt(R(2)SO)I (where R is ethyl or n-butyl) are twinned structures. The dinuclear species are the trans isomers. Two compounds of the type trans-Pt(DMSO)(amine)X(2) were studied by X-ray diffraction methods. The diiodo MeNH(2) compound forms H-bonded chains, formed by maximizing the H-bonds between the amine group with the O atom of DMSO and one iodo ligand. The H-bonding pattern is quite different in the dichloro t-BuNH(2) complex. In the latter crystal, there are two independent molecules which are H-bonded in pairs. The methyl groups of DMSO and the t-butyl group of the amine are oriented towards the outside of the pairs of molecules, while the H-bonds link the two independent molecules. Again, the amino group forms the maximum H-bonds with the O atom of DMSO and one chloro ligand. The crystal structures of trans-Pt(DMSO)(pyridine)I(2) and of trans-Pt(MeBzSO)(pyrimidine)I(2) (Bz = benzyl) were also studied. In the pyridine complex, the O atom of DMSO is in the Pt(II) plane by symmetry, while in the pyrimidine compound, the C atom of the -CH(3) group is in the Pt(II) plane. The pyridine and the pyrimidine ligands are perpendicular to the Pt(II) square plane. The trans influence of the different ligands is discussed. (C) 2007 Elsevier B.V. All rights reserved.
