Abstract Palladium(II) and platinum(II) complexes of the types PdLX2, PdL2X2, PtL2X2 and the Pt(IV) complexes PtLX2Y2, PtL2X2Y′2 (where L = mono- or bidentate organic ligand containing nitrogen donor atoms; X = Cl or Br; Y = Br and Y′ = OH) have been synthesized and characterized by elemental analysis, IR and X-ray photoelectron spectral data. The Pd 3d5/2 binding energies indicate that the 8-aminoquinoline
摘要PdLX2,PdL2X2,PtL2X2,Pt(IV)配合物PtLX2Y2,PtL2X2Y'2(其中L =含氮供体原子的单或双齿有机配体)的钯(II)和铂(II)配合物Br; Y = Br和Y'= OH)已合成并通过元素分析,IR和X射线光电子能谱数据表征。Pd 3d5 / 2的结合能表明,与其他研究的配体相比,8-氨基喹啉配体是金属的更好电子供体。在方形平面pd(II)配合物中的Cl 2p3 / 2结合能在198.0–199.56 eV范围内观察到。在红外光谱中观察到对应于两个顺式-Cl配体的ν(Pd)Cl)振动(ca 340和320 cm-1)。从UV差光谱数据暗示通过螯合形式的可能N-7的鸟嘌呤残基和磷酸氧结合。
