Summary: A new family of cationic, bidentate gold(III) fluoride complexes have been prepared and characterized, showing reactivity with cyano and acetylene nucleophiles. The resulting arylgold(III)C(sp) complexes exhibit higher rates of C(sp(2))-C(sp) bond formation compared to phosphine-based monodentate systems.

Summary: Ligand exchange reaction is a versatile post-synthesis modification method that plays an important role in thiolate-protected gold nanoclusters by adjusting the gold-sulfur interface. This process follows a SN2-like mechanism, supported by both experiments and calculations. Ligand exchange reaction can impart different functionalities and properties to gold nanoclusters.

Summary: This study reports the synthesis of a distannyne supported by a pincer ligand with pendant amine donors, which can activate E-H bonds at tin centers through dissociation of N-Sn donor/acceptor interactions. This chemistry allows the assembly of mixed-valence tin atom chains, with a decreasing propensity for chain growth as chain length increases, potentially due to the electron-withdrawing properties of the -Sn(Ar)H- backbone units generated via oxidative addition.

Summary: Metal nanoparticles stabilized with thiol-terminated polymers have various applications. The oxidation of surface metal atoms is proposed as a mechanism for the oxidative elimination of polymer from the nanoparticle surface. By reducing the oxidized metal surface and re-attaching thiol-terminated polymer ligands, the colloidal stability of polymer-capped metal nanoparticles can be improved and their redox stimuli-responsive self-assembly can be controlled.

Summary: This study presents a new class of organometallic compounds, dihydrodialanes supported by amidophosphine ligands. The ligand acts as a stereochemical reporter for reversible reductive elimination/oxidative addition chemistry involving Al-I and Al-III intermediates.

Summary: This study uncovers the role of the amidinate ligand in yielding two closely related copper hydride clusters with different catalytic hydrogenation activities. The researchers synthetized stable copper hydride clusters using ligand engineering strategy and observed reversible interconversion between the clusters triggered by solvent. Deuteration experiments demonstrated that the type of hydride in the clusters dictates the catalytic activity.

Summary: Recently, DNA-assembly nanoparticles based on DNA-metalion interactions have been developed for drug delivery and metal nanostructure synthesis. In this study, a new chemical strategy was developed to functionalize DNA-assembly nanoparticles with thiolated probe DNA, leading to the successful detection of multiple DNA targets.

Summary: Transformation chemistry has made significant advancements in synthesizing and functionalizing nanoclusters. However, the rational synthesis and understanding of structural evolution in nanoclusters are yet to be achieved. Recently, co-reactant-less transformations of nanoclusters have been revealed, triggered by various conditions such as pH, solvent, light, and temperature. In this perspective, the authors discuss how this unique transformation method contributes to the understanding of growth patterns and property evolution in nanoclusters.

Summary: This article demonstrates the isomer-selective conversion of Au-18(ScC6)(14) into Au-24(SR)( x )(ScC6)(20-x ) by reactions with gold(I) thiolate complexes. The results suggest that the number of AuSR units increases in the surface Au(I)SR oligomers, while the number of electrons in the Au core remains constant. This discovery provides an important synthetic route for rational design.

Summary: We demonstrate a simple route to recycle gold nanoparticle (Au NP) catalysts by altering surface wettability. The hydrophilic Au NPs were used to catalyze the reduction of 4-nitrophenol (4-NP) and then separated from the suspension by interfacial ligand exchange. The catalyst was regenerated through reversible ligand exchange.

Summary: A well-defined thiolate-bridged cobalt-ruthenium complex reversibly binds N-2 by modulation of the auxiliary phosphine ligand, as evidenced by time-dependent H-1 NMR spectroscopy at different temperatures. Notably, this heterobimetallic system represents the first example of N-2 coordination on a sulfur-rich Co-Ru cooperative scaffold.

Summary: Silver nanoparticles are widely used for their antimicrobial activities, but they can become toxic in natural or biological environments due to the dissolution of Ag(i) ions. This study synthesized and characterized new silver thiolate coordination polymers (CPs) that undergo a reversible 2D-to-1D structural transformation in the presence of excess thiol molecules. The study also highlights the dissolution-recrystallization mechanism of these silver-thiolate CPs in different media upon thiol exchange reactions.

Summary: Gold nanoparticles have been extensively studied due to their stability, physicochemical properties, and applications. Achieving atomic precision control over gold nanoparticles is crucial for understanding their structures, properties, and applications. While some ultrasmall gold nanoparticles have been partially realized, the design and synthesis of gold nanoparticles with atomic precision remain distant goals.

Summary: Microbial manganese oxidation is important in the formation of Mn(III/IV) oxides in environmental systems. The presence of sulfonic acids can affect Mn biogeochemical cycling and microbial Mn oxidation processes. This study investigated the impact of sulfonic acids on fungal Mn oxidation and found that they can promote or suppress Mn oxidation depending on the fungus species. These findings highlight the sensitivity of Mn oxide structures and the Mn oxidation process to the aqueous environment.
