最近提出了一个大统一模型（GUM）来理解配位金团簇的结构解剖和演化。除了三角形Au-3（2 e）和四面体Au-4（2 e）两种基本块体外，我们还引入了一种次级块体，即具有8 e价电子的二十面体Au-13，记为Au-13（8 e）。利用该次级块体，可以方便地分析一组特殊的含二十面体Au-13基序的配体金纳米团簇的结构解剖和演化。此外，一个新的配体保护的簇合物Au-49（PR 3）（10）（SR）（15）Cl-2被预测具有高的化学稳定性和热稳定性，表明它可能在实验室中合成。(C)2017爱思唯尔B. V.保留所有权利。
A grand unified model (GUM) has been proposed recently to understand structure anatomy and evolution of liganded gold clusters. In this work, besides the two types of elementary blocks (triangular Au-3(2e) and tetrahedral Au-4(2e)), we introduce a secondary block, namely, the icosahedral Au-13 with 8e valence electrons, noted as Au-13(8e). Using this secondary block, structural anatomy and evolution of a special group of liganded gold nanoclusters containing icosahedral Au-13 motifs can be conveniently analyzed. In addition, a new ligand-protected cluster Au-49(PR3)(10)(SR)(15)Cl-2 is predicted to exhibit high chemical and thermal stability, suggesting likelihood of its synthesis in the laboratory.
