Article Abstract

Polyoxometalate (POM)-encapsulated Ag nanoclusters have attracted increasing research interest due to their intriguing structural diversities and synergistic catalytic properties; however, the types of POM ligands are limited to the multidentate lacunary or ring-shaped POMs. Herein, we develop an asymmetric POM-induced synthetic strategy to synthesize a superatomic {Ag} cluster encapsulated by six redox-active mixed-addendum ligands, (CHN)NaH[NaAg(PWNbO)]·36CHCN (). The oriented aggregation of Ag ions is attributed to the unevenly distributed electron density over the asymmetric mixed-addendum ligands. The resulting cluster exhibits interesting photothermal and photocatalytic performance due to the redox activity of ligands. This work presents a new research avenue for the construction of Ag nanoclusters induced by asymmetric all-inorganic POM ligands and will stimulate the structural exploration and catalytic applications of atomically precise metal nanoclusters.

Tailoring the electrocatalytic hydrogenation (ECH) performance of silver nanoclusters at the atomic level remains challenging. A mixed-ligand-protected superatomic silver nanocluster, Ag(PNP)(-TBBT) () (PNP= 2,6-bis(diphenylphosphino)pyridine; -TBBT = 4--butylthiophenol), was synthesized, and its structure was determined by single-crystal X-ray diffraction (SCXRD). consisted of a capped icosahedral Ag kernel and accessible Ag(RS) and Ag(RS) motifs.

Incorporating lower-valent heterometal dopants into ligand-protected superatomic metal clusters is a key strategy for tuning their optical properties and stability. However, the precise doping effects in such clusters remain poorly understood. In this study, three pairs of 8-electron superatomic alloy clusters stabilized by diphosphine ligands: one pair with 1,3-bis(diphenyphosphino)propane ligand ([MAg(DPPP)Cl](OTf), abbr.

Atomically precise monolayer-protected coinage metal nanoclusters (CMNCs) have drawn increasing attention for their diverse structures and intriguing properties. Nevertheless, not all-N-heterocyclic-carbene (NHC)-protected atomically precise silver nanoclusters have been synthesized yet. Herein, we report the synthesis and crystal structure of the first all-NHC-protected superatomic silver cluster.

Ligand and Metal Exchanges between [(AuAg)(SR)] Clusters via Bimolecular Superatomic Collision.

Reported herein is a study of intercluster exchanges of ligands and/or metals between [(AuAg)(SR)] nanoclusters via a combination of electrospray ionization mass spectrometry, X-ray crystallography, and UV-vis spectroscopy. The results revealed that ligand exchange reactions are instantaneous, giving rise to the standard Gaussian distribution indicative of a random exchange or substitution process. In sharp contrast, metal exchange reactions are slow (hours to days), resulting in fractal-like patterns.
