Summary: SLHN with K2NiF4-type structure exhibits high hydride ion conductivity. The structure of SLHN consists of hydride ions occupying equatorial and apical sites, while nitride ions preferentially occupy apical sites, with a substantial amount of anion vacancies observed. By partially substituting nitride ions with oxide and hydride ions, the electrical conductivity of SLHN can be further enhanced.

Summary: A protocol for regio-controlled hydromagnesiation of 1,3-enynes was developed using magnesium hydride generated in situ by solvothermal treatment of sodium hydride and magnesium iodide in THF. The resulting allenylmagnesium species could be converted into tri- and tetra-substituted allenes by subsequent treatment with various carbon- and silicon-based electrophiles with the aid of CuCN as a catalyst.

Summary: The study synthesized carbon-rich C-S-H compounds using methane and determined their structure and composition through Raman spectroscopy and single-crystal x-ray diffraction, revealing the presence of methane molecules substituting hydrogen sulfide molecules. The structural behavior of the compounds undergoes transitions at different pressures and demonstrates a distortion into a Pnma structure at 132-159 GPa before transforming into a common H3S phase at higher pressures. However, no structural anomaly is detected near 220 GPa, where a sharp increase in T-c has been reported.

Summary: An effective one-pot reduction method was used to synthesize a novel and stable layered Cu nanocluster. The cluster, with a molecular formula of [Cu-14((BuS)-Bu-t)(3)(PPh3)(7)H-10]BF4, exhibits different structures from previously reported analogues and shows intrinsic chirality due to non-covalent ligand-ligand interactions. This cluster has potential applications in drug filling and gas adsorption, thanks to the formation of interlacing chiral-cluster enantiomers and the self-assembly of nanostructures.

Summary: Intermetallic compounds based on rare-earth metals and iron are the most promising materials for permanent magnets. In this study, the hydride Sm1.2Ho0.8Fe17H4.4 was prepared by direct hydrogenation of the intermetallic compound Sm1.2Ho0.8Fe17, with a high hydrogen content. The hydrogenation increased the saturation magnetization at room temperature but did not significantly affect it at low temperature. Additionally, a spin-reorientation phase transition was observed in the hydride under high magnetic fields.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
