  由二硫醇保护的同质铂/银超原子：两个和三个中心二十面体与 Ne2 和 I3- 的线性组合

  摘要：

  三个双金属铂/银纳米簇，PtAg20(dtp)12 (1)、Pt2Ag33(dtp)17 (2) 和 Pt3Ag44(dtp)22 (3)（dtp：二硫代磷酸二丙酯），簇电子数分别为 8、16 和22 分别是通过一相共还原方法生产的。单晶 X 射线结构表明，它们的内核可以分别可视化为由一个、两个和三个中心二十面体 Pt@Ag12 单元组成。在（2）和（3）中，这些单元共享顶点并线性组装。有趣的是，22 电子合金 (3) 与线性三碘化物阴离子 I3- 是等角的，并且代表了由三个超原子组成的团簇的第一个例子，其键合特性类似于三原子分子物种的键合特性。

  Synthesis and characterization of liquid platinum compounds

  摘要：

  Liquid platinum complexes were obtained with a ligand with alkyl chains that attach to the coordination plane perpendicularly and herewith render a close packing of the molecules difficult for certain chain lengths. Bis(O, O'-dialkyldithiophosphato)platinum(II) complexes, Pt(C(x)dtp)(2) where the alkyl chains are methyl (x = 1), ethyl (x = 2), propyl (x = 3), butyl (x = 4), pentyl (x = 5), hexyl (x = 6), heptyl (x = 7), dodecyl (x = 12), and octadecyl (x = 18), were investigated. The platinum compounds were synthesized via two routes: reaction of tetrachloroplatinate(IT) with ammonium-O,O'-dialkyldithiophosphates or oxidative addition of (O,O'-dialkylthiophosphoryl)disulfides to tris(styrene)platinum(0). The melting temperatures as a function of the alkyl chain length show a minimum for the complex with pentyl groups. The complexes with pentyl and hexyl groups are liquid at room temperature, and the complexes with butyl and heptyl groups melt only slightly above room temperature. Depending on the complex, the low melting temperatures are induced by an unfavorable packing of the molecules in the solid state, reflected in a low melting enthalpy, or melting entropy. The molecular weights of the liquid complexes are between 700 and 800 and, therefore, extraordinarily high for liquid metal compounds. Depending on the alkyl groups, the complexes decompose at 172-241 degrees C. Crystals of bis(O,O'-diethyldithiophosphato)platinum(II), Pt(C(2)dtp)(2), are monoclinic, space group P2(1)/n, a = 8.90, b = 8.70, c = 12.45 Angstrom, alpha = gamma = 90 degrees, beta = 100.89 degrees, and Z = 4.
