Summary: The reactivities of interstitial hydrides are difficult to explore compared to surface hydrides. By treating with metal ions, the stable Cu-I dihydride template can generate three very different compounds, including the first appearance of a trigonal pyramidal hydride coordination mode in compound 2.

Summary: The reaction of [Au(tht)(2)](ClO4), [Cu(CH3CN)(4)](ClO4), 3,6-di-tert-butyl-1,8-diethynyl-9H-carbazole (H(3)decz), and bis(2-diphenylphosphinophenyl)ether (POP) in the presence of triethylamine (NEt3) yielded the cluster complex Au4Cu2(decz)(2)(POP)(2) as yellow crystals. The Au4Cu2 cluster exhibits a scissor-like structure sustained by two decz and two POP ligands and stabilized by Au-Cu and Au-Au interactions. The cluster shows bright yellow to orange photoluminescence and exceptional thermochromic phosphorescence characteristics.

Summary: Atom precise metal nanoclusters with customized surface structures play an important role in understanding surface engineering mechanisms for specific applications. In this study, a single copper atom doping was performed on a widely studied Au11(PPh3)7Cl3 nanocluster, resulting in the formation of a bimetal nanocluster Cu1Au11(PPh3)7Cl2 with a unique Au-Cu surface motif. The unsaturated copper atom in this motif acts as an active catalyst for Sonogashira reaction, showing reversed selectivity compared to the catalytically inactive Au11 nanocluster. Theoretical calculations support the unsaturated Cu atom as the active site and a single-atom catalyst in the nanocluster.

Summary: [Cu(I)4(hedtc)4] center dot 4THF ( 1 ) and [In(III)(hedtc)3] center dot 3THF ( 2 ) complexes were successfully synthesized from reactions of Cu(II)Cl2 Greek ano teleia2H2O, In(III)CI3, and NH4(hedtc) in aqueous solution. These complexes are soluble in polar organic solvents due to the hydroxy group in the hedtc ligand. Compound 1 forms a tetranuclear cluster with copper-copper metal bonds and a copper-sulfur coordination environment, while compound 2 has indium bound to three hedtc ligands with distorted octahedral coordination. Both compounds contain tetrahydrofuran (THF) solvent molecules participating in hydrogen bonding.

Summary: Crystal growth from anhydrous hydrogen fluoride solutions of M2+ (M=Cu, Ag) and [AuF6](-) yielded M(AuF6)(2) salts (M=Cu, Ag), while attempts to prepare single crystals of the corresponding nickel, zinc, and magnesium salts were unsuccessful. The crystal structure of Cu(AuF6)(2) consists of layered slabs formed by the connection between Cu2+ cations and [AuF6](-) anions through van der Waals interactions. The crystal structure of Ag(AuF6)(2) is a three-dimensional framework where Ag+ cations are linked by [AuF6](-) anions. Both structures belong to the M-II((XF6)-F-V)(2) family, which has seven observed structure types. In the crystal structure of O-2(CuF)(3)(AuF6)(4) center dot HF, bridging AuF6 units connect [-Cu-F-Cu-F-](infinity) chains to form stacks, with O-2(+) cations and HF molecules located between the stacks.

Summary: A catalyst containing atomically dispersed Pd sites on N-heterocyclic carbene (NHC)-stabilized Au nanoclusters has been developed for efficient and regioselective hydrogenation of alkenes. The unique molecular structure of the catalyst allows the Pd atom to activate molecular hydrogen and catalyze the hydrogenation reaction effectively. However, the catalyst shows lower activity towards crowded alkenes due to the stringent steric requirements of the NHC ligands.

Summary: Gravity is the weakest fundamental force and remains a challenge to unify with the standard model of physics. Testing gravity at different scales is important, with current tests mainly focusing on macroscopic masses at the kilogram scale and beyond. This study demonstrates gravitational coupling between small gold spheres, expanding the parameter space of gravity measurements to small source masses and low gravitational field strengths.

Summary: Nanoporous gold, obtained by corrosion of gold alloys, has diverse applications. However, if the corrosion conditions are not optimized, the dealloying process can lead to partially porous samples. In this study, we investigate the interface between porous material and non-porous alloy in two samples, where dealloying either stopped automatically or was manually interrupted. Possible reasons for unintended termination of dealloying in the former case are suggested.

Summary: Density functional theory calculations were used to investigate the reaction mechanism of benzyl alcohol aerobic oxidation catalyzed by Au and Au-Pd clusters, with the findings showing that Au plays a crucial role in activating molecular oxygen and benzyl alcohol. Meanwhile, Pd in the Au6Pd2 cluster increases electron distribution to neighboring Au atoms, leading to lower energy barriers in the reaction.

Summary: This study investigated the synthesis and structural characterization of six new [HgTe]-based cluster compounds derived from bis(2-pyridyl)ditellane and different mercury salts. Various techniques, including single-crystal X-ray diffraction and FT-IR spectroscopy, were used to study the compounds, and their optical properties were evaluated by solid-state UV-Vis diffuse reflectance spectroscopy. The results showed a strong dependence of the optical properties on the core structure's size and composition, with smaller core structures presenting larger energy gap values.

Summary: A novel Mo-catalyzed carbonylative Sonogashira cross-coupling between 2-iodoglycals and terminal alkynes is reported herein. The reaction shows significant improvements compared to a previously published Pd-catalyzed procedure by allowing the use of unprotected sugar derivatives as starting materials and tolerating substrates with chelating groups. The utility of the glyco-alkynone products as a platform for further functionalization is also demonstrated by synthesizing glycoflavones via Au-catalyzed 6-endo-dig cyclization.

The optimized conditions yielded moderate to good yields of glycal amides. Furthermore, the acetyl groups in the glycal amides could be easily removed, resulting in the corresponding trihydroxy derivatives.

Summary: The zwitterionic compounds, such as pyridine-containing tellurenyl compounds, are versatile building blocks for heterometallic assemblies. Reactions of these compounds with the rhenium(V) complex result in the formation of [ReO2Cl(pyTeCl)(PPh3)(2)] and [ReO2Cl(CF(3)pyTeCl)(PPh3)(2)], which exhibit elongated Re-O bonds and Te-O contacts. The oxidation states of the metal ions are ambiguous, and DFT calculations suggest the formation of a Re(V) dioxide complex donating into an organotellurium(II) chloride.
