  摘要：

  在乙腈中用三酸银取代[PtI2(dpa)](1)复合物（dpa 是 2,2′-二吡啶基胺）中的碘配体，得到了[Pt(dpa)(MeCN)2](SO3CF3)2 (2)。在甲醇（X = NO3）或乙腈（X = SO3CF3）中，在银盐 AgX 的存在下，用 2,2′-二吡啶胺处理[PtI2(dpa)]（1），合成了均质配合物[Pt(dpa)2](X)2 (3-(X)2)。复合物[3](SO3CF3)2 的去质子化得到同质复合物[Pt(dpa-H)2](4)的方法有两种，例如在甲醇中用 2 等量的 NaOH 处理[3](SO3CF3)2，或在甲醇中向[3](SO3CF3)2 的悬浮液中加入过量 Et3N。化合物 1-4 的结构是通过元素分析、高分辨率电喷雾电离质谱、红外光谱和核磁共振光谱确定的；复合物 [2](SO3CF3)2、[3](NO3)2-H2O、[3](SO3CF3)2-2H2O 和 4 的晶体结构是通过单晶 X 射线衍射确定的。

  Six novel platinum(II) and palladium(II) complexes with */ cisplatin */ analogous configuration were prepared and could be obtained as single crystals for X-ray structure analyses. The ligand system based on 2,2?-dipyridylamine was extended stepwise by adding alkyl chains to the bridging nitrogen atom, starting from pure 2,2?-dipyridylamine to (2,2?-dipyridyl)-n -butylamine.

  The nitrile complex [Pt(dpa)(NCNMe2)(2)](SO3CF3)(2)center dot 2H(2)O (2 center dot 2H(2)O) was prepared by treatment of [PtI2(dpa)] with AgSO3CF3 in dimethylcyanamide. When the abstraction of the iodide ligand was performed in a RCN-MeOH mixture, the imino ester complexes [Pt(dpa)NH=C(OMe)R}(2)](SO3CF3)(2) (R = Me 3, NMe2 4) were formed and these species were isolated in 76% and 70% yields, respectively. Complexes 3 and 4 were also generated when [Pt(dpa)(NCMe)(2)](SO3CF3)(2) (1) and 2 center dot 2H(2)O, correspondingly, were dissolved in MeOH. The formulation of complexes was supported by agreeable ESI+-MS, IR, H-1 and C-13H-1} NMR spectroscopies; the structure of 4 was determined by the single-crystal X-ray diffraction.

  AbstractThe treatment of cis‐[Pt(dpa)(RCN)2][SO3CF3]2 dpa = 2,2′‐dipyridylamine, R = Me, Et, CH2Ph, Ph; [2a–d](OTf)2} (OTf = SO3CF3) with 2 equiv. of N,N′‐diphenylguanidine [NH=C(NHPh)2] in CH2Cl2 solutions at room temp. for 16 h gives [Pt(dpa)NH=C(R)NC(NHPh)=NPh}][SO3CF3] [3a,b,d](OTf)} as the addition products and [Pt(dpa)NH=C(R)NHC(R)=NH}][SO3CF3]2 [4a,b](OTf)2} as the tailoring products. The formulation of complexes [3a,b,d](OTf) and [4a,b](OTf)2 was supported by satisfactory C, H, and N elemental analyses and agreeable high‐resolution ESI‐MS, IR, and 1H (including 1H–1H COSY experiments) and 13C1H} NMR data. The structures of all of the platinum species were determined by single‐crystal X‐ray diffraction. The resultant complexes are nonemissive in solution, mainly because of the interaction between the empty d orbital in a square‐planar configuration and solvent molecules. However, in the solid state, complexes [3a,b,d](OTf) exhibit strong phosphorescence with quantum yields (peak wavelength) of 0.23 (490 nm), 0.27 (483 nm), and 0.20 (532 nm), respectively.
