Summary: This study describes the synthesis and characterization of two novel molecular organotelluroxane clusters. The addition of specific functional groups to the tellurium centers enables chalcogen bonding halide template directed assembly. These molecular clusters have excellent solubility in organic solvents and remarkable chemical stability, and they also exhibit aggregation induced emission behavior in organic aqueous solvent mixtures.

Summary: Photoirradiation of a pyridine solution of Ag-29 nanoclusters with red photoluminescence at 680 nm activated intense photoluminescence in the near infrared (NIR) region, with a quantum yield of 33% at 770 nm. The use of Au-doped silver nanoclusters further increased the quantum yield to over 45% at 800 nm. Photoirradiation is believed to alter the charge localization in nanoclusters, leading to the formation of sites emitting near infrared light.

Summary: This study introduces a new enantiomeric pair of superatomic silver clusters, R/S-Ag-17, prepared from chiral alkynyl ligands, which exhibit near-infrared emission and circularly polarized luminescence. Experimental and theoretical evidence suggest that the CPL originates from transitions between superatomic 1P(z) and 1S orbitals. This work paves the way for the development of CPL-active metal nanoclusters utilizing chiral ligands and demonstrates the transfer of chirality from protecting ligands to superatomic states in metal clusters.

Summary: Scanning transmission electron microscopy experiments confirm that the predominant ordered structure for Ag309 nanoclusters is face-centered cubic (FCC). Density functional theory calculations reveal the influence of defects and symmetry changes on stability, with FCC and decahedral symmetries being more favorable than icosahedral. The proposal of a surface atomic density descriptor provides a qualitative reproduction of surface energy data, indicating that nonsymmetric and defective structures may be preferred within a certain size range.

Summary: The Cambridge Structural Database was used to evaluate crystals containing Se⋯O chalcogen bonding interactions. These interactions can operate independently of complementary intermolecular interactions, with one-dimensional and zero-dimensional assemblies being the most prominent in around 55% and 30% of cases, respectively. Specific interactions, such as Se⋯O(carbonyl), occur in 50% of cases where they can potentially form.

Summary: The Cloke-Wilson rearrangement is a significant method for constructing heterocycles, traditionally facilitated by strong Lewis acids, Bronsted acids, and Lewis bases. However, a weak interaction catalysis approach to this rearrangement has remained challenging and unreported. This study presents a chalcogen bonding catalysis method using double SeO interactions to activate carbonyl cyclopropanes and achieve the Cloke-Wilson rearrangement. This alternative strategy successfully yields a wide range of dihydrofurans, providing a new approach for catalyzing the Cloke-Wilson rearrangement.

Summary: This article describes the formation of superatoms by nanoclusters of Group 11 metals stabilized by dichalcogenido and hydrido ligands, and their relationship with precursor hydrido clusters. It is found that the formation of superatoms involves the loss of hydrides and release of H-2 gas, indicating internal self-redox reactions that require a similar core structure.

Summary: A neutral polyhydrido copper cluster, [Cu27H15], was prepared by reacting dithiocarbamates, Cu(i) salts, and NaBH4. The cluster has a core-shell structure with an outer Cu-24 rhombicuboctahedral cage and an inner Cu-3 triangular kernel. Core engineering allows for the reversible transition between an irregular Cu-4 tetrahedron and a Cu-3 triangle, while maintaining the outer Cu-24 shell intact.

Summary: This study reports the synthesis and characterization of a series of atomically defined dithio- and diselenophosphate-protected eight-electron superatomic palladium-doped silver nanoclusters, including an unprecedented pair of selenolate-protected isomers. The solid state structures revealed different metal frameworks from the parent cluster due to the distribution of capping silver(I) atoms around a Pd@Ag-12 centered icosahedron with different symmetries. The crystallization of the reaction product led to the co-crystallization of two isomers in the unit cell, a first among selenolate-protected nanoclusters.

Summary: The first hydride-containing 2-electron palladium/copper alloys, PdHCu11 and PdHCu12, were synthesized. X-ray diffraction reveals that the PdHCu11 and PdHCu12 kernels consist of a central PdH unit encapsulated within a vertex-missing Cu-11 cuboctahedron and complete Cu-12 cuboctahedron, respectively. PdHCu11 shows excellent HER activity, with an onset potential of -0.05 V (at 10 mA cm(-2)) and consistent HER activity during 1000 cycles in 0.5 M H2SO4.

Summary: The first 8-electron Pd/Ag superatomic alloys with an interstitial hydride [PdHAg19(dtp)(12)] and [PdHAg20(dtp)(12)](+) are reported. Addition of a single Ag atom to [PdHAg19(dtp)(12)] through the reaction of trifluoroacetic acid yields [PdHAg20(dtp)(12)](+) in 55% yield. Further modification of the shell results in the formation of [PdAg21(dtp)(12)](+) via an internal redox reaction. The interstitial hydride in [PdHAg19(dtp)(12)] and [PdHAg20(dtp)(12)](+) contributes its 1s(1) electron and occupies a PdAg3 tetrahedron.

Summary: Three unknown rhodium/silver alloy nanoclusters with eight electrons, [RhAg21{S2P((OPr)-Pr- n )(2)}(12)] (1), [RhHAg20{S2P((OPr)-Pr- n )(2)}(12)] (2), and [RhH2Ag19{S2P((OPr)-Pr- n )(2)}(12)] (3), were discovered and characterized. Cluster 1 has a regular Rh@Ag-12 icosahedral core, while clusters 2 and 3 have distorted RhH@Ag-12 and RhH2@Ag-12 icosahedral cores respectively. The insertion of one hydride dopant eliminates one capping silver atom on the cluster surface, resulting in the general formula [RhH x @Ag21-x {S2P((OPr)-Pr- n )(2)}(12)] (x = 0-2). Clusters 1-3 exhibit intense emissions in the near-infrared region, with involvement of the encapsulated heterometal's 4d orbitals in the optical processes.

Summary: This study characterizes two structures using high-quality single-crystal X-ray crystallography and accurately determines the position of interstitial hydrides. Anisotropic refinement of the hydrides was successfully achieved. The distances between the central atom and copper atoms, as well as within the surrounding metal cages, were analyzed and compared with similar compounds. This work offers a thoughtful and accurate assessment of the considerations and challenges associated with anisotropic refinement for H atoms in X-ray data collection.

The waist part of the cluster is bridged by three dithiocarbamate ligands, each exhibiting a hexaconnective, hexametallic (mu(3), mu(3)) coordination pattern, which is an unprecedented feature in Cu nanocluster chemistry.
