Horizontal expansion of biicosahedral M₁₃-based nanoclusters: resolving decades-long questions

Abstract

For metal nanoclusters with the “cluster of clusters” intramolecular evolution pattern, most efforts have been made towards the vertical superposition of icosahedral nanobuilding blocks (e.g., from mono-icosahedral Au13 to bi-icosahedral...

Staggered Assembly of a Dimeric Au13 Cluster: Impacts on Coupling of Geometric Isomerism

“…Linear bi‐icosahedral, tri‐icosahedral, and tetra‐icosahedral superclusters have been prepared [14,19–49] . Among homogold clusters, the first linear dimer comprised of Au 13 blocks, [Au 25 (PPh 3 ) 10 (SC 2 H 5 ) 5 Cl 2 ] 2+ , was synthesized with E configuration by Tsukuda et al.…”

Tailoring two magic number Au13 nanoclusters with N-containing diphosphine ligands: a classical icosahedral core vs. an unprecedented UFO- shaped core

“…Au 13 NCs have been used as a superatom unit to construct quite a few "superatomic molecules". 20,21 These ultrasmall gold clusters are promising candidates for novel materials and have potential applications in the fields of catalysis, fluorescence, biomedical imaging, and sensing, due to their unique structural features and interesting physicochemical properties. [22][23][24][25][26][27][28][29][30][31][32][33][34][35] Organophosphine is one of the earliest and common ligands used in the synthesis of gold NCs.…”
