Abstract:
Atomically precise clusters of group 11 metals (Cu, Ag, and Au) attract considerable attention owing to their remarkable structure and fascinating properties. One of the unique subclasses of these clusters is based on dichalcophosphate ligands of [(RO)2PE2]- type (E = S or Se, and R = alkyl). These ligands successfully stabilise the most diverse Cu, Ag, and Au clusters and superatoms, spanning from simple ones to amazing assemblies featuring unusual structural and bonding patterns. It is noteworthy that such complicated clusters are assembled directly from cheap and simple reagents, metal(I) salts and dichalcophosphate anions. This reaction, when performed in the presence of a hydride or other anion sources, or foreign metal ions, results in hydrido- or anion-templated homo- or heteronuclear structures. In this feature article, we survey the recent advances in this exciting field, highlighting the powerful synthetic capabilities of the system \"a metal(I) salt - [(RO)2PX2]- ligands - a templating anion or borohydride\" as an inexhaustible platform for the creation of new atomically precise clusters, superatoms, and nanoalloys.
摘要:
原子精确的第11族金属团簇(Cu,Ag,和Au)由于其出色的结构和引人入胜的特性而引起了极大的关注。这些簇的独特亚类之一基于[(RO)2PE2]型的二磷酸盐配体(E=S或Se,和R=烷基)。这些配体成功地稳定了最多样化的Cu,Ag,Au团簇和超原子,从简单的到惊人的组件,具有不寻常的结构和粘合模式。值得注意的是,这种复杂的簇是由廉价和简单的试剂直接组装而成的,金属(I)盐和二磷酸根阴离子。这个反应,当在氢化物或其他阴离子源存在下进行时,或者外来金属离子,导致氢化物或阴离子模板的均核或异核结构。在这篇专题文章中,我们调查了这个令人兴奋的领域的最新进展,突出了“金属(I)盐-[(RO)2PX2]-配体-模板阴离子或硼氢化物”系统的强大合成能力,作为创建新的原子精确簇的取之不尽的平台,超原子,和纳米合金。
