A New Crystal Structure of Au₃₆ with a Au₁₄ Kernel Cocapped by Thiolate and Chloride

Abstract

This study presents a new crystal structure of a gold nanocluster coprotected by thiolate and chloride, with the formula of Au36(SCH2Ph-(t)Bu)8Cl20. This nanocluster is composed of a Au14 core with two Cl atoms, a pair of pentameric Au5(SCl5) staple motifs, and a pair of hexameric Au6(S3Cl4) motifs. It is noteworthy that the "Au-Cl-Au" staple motifs are observed for the first time in thiolate protected gold nanoclusters. More importantly, the formation of the Cl-Au3 motifs is found to be mainly responsible for the configuration of the gold nanocluster. This work will offer a new perspective to understand how the ligands affect the crystal structure of gold nanocluster.

Selective Gold Recovery and Catalysis in a Highly Flexible Methionine-Decorated Metal–Organic Framework

“…The average Au-S bond distances of 2.75(7) (Au Au Au Au I are somewhat longer than those reported so far for Au III whereas the Au-Cl ones of 2.50(7) (Au Au Au Au I , fall in the typical range of related gold(I) and gold(III) compounds found in the literature [27][28][29]. Aurophilic interactions 30 are present in Au the shortest Au···Au separations being 3.04(2) Å (Figures S4-S5).…”

A grand unified model for liganded gold clusters

“…A grand challenge to scientists in this field, however, is the precise determination of atomic structures of liganded gold clusters. To date, atomic structures of tens of liganded gold clusters have been determined via X-ray crystallography56789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263. Nevertheless, these revelations appear serendipitous as the structural determination largely hinges on availability of single crystals for the liganded gold clusters.…”

Amphiphilicity Regulation of AgI Nanoclusters: Self‐Assembly and Its Application as a Luminescent Probe

“…Metal nanoclusters (NCs, including copper, silver and gold NCs) with atomic precision are small particles composed of a metal core and a ligand shell with a total size of less than 2 nm . The metal NCs show excellent properties in several fields, such as sensors, biological sciences, and catalysis . In particular, the photoluminescent nature of metal NCs attracts significant attention from research workers.…”

“…[1,2] The metal NCs show excellent properties in several fields, such as sensors, biological sciences, and catalysis. [3][4][5][6] In particular, the photoluminescent nature of metal NCs attracts significant attention from research workers. Compared with common luminescent materials, such as quantum dots andf luorescent organic molecules,m etal NCs are nontoxic,h ighly photostable, and their preparation is simple, which make them suitable candidates for bioimaging.…”
