The development of rational synthetic routes to inorganic arsenide compounds is an important goal because these materials are finding applications in many areas of materials science. In this paper, we show that the binary crown clusters [M@As] (M = Nb, Ta) can be used as synthetic precursors which, when combined with ZnMes, generate ternary intermetalloid clusters with 12-vertex cages, {M@[As(ZnMes)]} (M = Nb, Ta). Structural studies are complemented by mass spectrometry and an analysis of the electronic structure using DFT. The synthesis of these clusters presents new opportunities for the construction of As-based nanomaterials.
开发无机砷化物化合物的合理合成路线是一个重要目标，因为这些材料在材料科学的许多领域都有应用。在本文中，我们表明二元冠簇[M@As]（M = Nb，Ta）可用作合成前体，当与ZnMes结合时，会生成具有12个顶点笼的三元类金属簇{M@[As(ZnMes)]}（M = Nb，Ta）。通过质谱分析和使用DFT对电子结构的分析对结构研究进行了补充。这些簇的合成为基于砷的纳米材料的构建提供了新的机会。
