“…Atomically precise metal nanoclusters with a crystal structure determined remain a unique class of nanomaterials in terms of their role in illustrating structure–property relationships. − With size, composition, and structure precisely determinable and readily tunable, metal nanoclusters have found wide applications in fields including catalysis, biology, and electronics. − Such nanocatalysts with molecular characteristics have especially been regarded as model systems to probe catalytically active sites and uncover the reaction mechanism of nanocatalysis at the molecular level. − The past several decades have thus witnessed significant efforts in optimizing the activity, selectivity, and stability of cluster-based catalysts in various chemical transformations via multiple strategies such as ligand engineering, composition tuning, and structure tailoring. − In the progress, the reactions have been extended from thermal catalysis and electrocatalysis to photocatalysis, ligands from phosphine, thiol, and alkynyl to N -heterocyclic carbene, and metals from gold, silver, and copper to platinum and palladium. ,− ,− …”

Copper nanostructures represent an important class of materials in CO2 electrocatalytic reduction (CO2ER) reactions, but deciphering their molecular structures, especially those with multiple and irregular organic–inorganic interfaces, remains a grand challenge. Through comprehensive characterization of a 26-nuclei copper nanocluster of [Cu26(DPPE)3(CF3CO2)8(CH3O)2(tBuCC)4H11]+ (DPPE is 1,2-bis(diphenylphosphino)ethane), which is stabilized by quintuple ligand shells of phosphine, carboxylic acid, alcohol, alkynyl, and hydride, we demonstrate in this work the efficiency of hybrid ligands in controlling geometrical arrangements, electronic structures, and catalytic performance of copper nanoclusters. The diverse ligands in the cluster endow it with a peculiar geometric structure and distinct electronic structure and, more importantly, a delicate surface structure. As a result, the cluster displays high performance in CO2ER to CO reaction.

The construction of C−S bonds is of great importance in the field of synthetic and medicinal chemistry. Herein, solvent-induced umpolung reactions from dioxygenation to interligand C−S cross-coupling in bis(cyclometalated) Ir(III) thiolate complexes are reported in good to excellent yields at room temperature. Specifically, the reaction of rac-[Ir(pq) 2 (aet)] (where pq is 2-phenylquinoline and aet is 2-aminoethanethiolate) can be selectively switched to dioxygenation in acetonitrile solution in the presence of O 2 , resulting in the formation of a sulfinato complex rac-[Ir(pq) 2 (aes)] (where aes is 2-aminoethanesulfinato). Alternatively, the reaction in trifluoroethanol solution leads to interligand C−S cross-coupling, affording a rac-[Ir(pq)(pqaet)](PF 6 ) [where pqaet is 2-((2-phenylquinolin-8-yl)thio)ethan-1amine] complex, which generates a new tetradentate ligand in situ. Mechanistically, the formation of electrophilic metal thiyl radicals is proposed as a key intermediate in the interligand C−S coupling reaction. Furthermore, the sequential oxidation of a thioether complex into a sulfoxide complex is also observed at room temperature using H 2 O 2 as an oxidant. Additionally, a new approach for the synthesis of a hexadentate ligand is developed through sequential C−S and C−N interligand coupling of metal thiolate complexes in situ under visible light irradiation in the presence of O 2 .
