Summary: The Cu(II)-(L-CF3)(2) complex exhibits a distorted seesaw geometry with the shortest crystallographic CF center dot center dot center dot Cu distances reported to date, likely due to specific ligand interactions. This distortion may have a steric origin according to comparisons with other versions of the complex.

Summary: Three coordination compounds were synthesized and characterized from the reaction of copper(ii) bromide with the flexible bis-tetrazole organosulfur ligand, 1,2-bis(1-methyl-1H-tetrazole-5-ylthio)ethane (bmtte). Different reaction conditions led to the formation of polymeric 2 & INFIN;Cu2Br4(bmtte) (1), trinuclear [Cu3Br4(bmtte)(2)] (2), and tetranuclear [Cu2Br2(bmtte)](2) (3) compounds with different structures. The thermal stability, aqueous behavior, and reactivity of the compounds were investigated, and a new polymeric compound (8Cu4I4)-Cu-2(bmtte)(2) (4) was prepared through solid-state reaction and microwave irradiation. The redox behavior of the compounds was analyzed by cyclic voltammetry.

Summary: Copper homeostasis is crucial for mammal's health and its dysregulation is implicated in diseases like Alzheimer's. In this study, a novel peptide-based copper shuttle is designed, which can selectively transport copper ions into cells and remove copper from amyloid plaques, inhibiting oxidative stress and cell toxicity. This mechanism shows potential applications in treating copper-related diseases.

Summary: In this study, we present the solid-state characterization of an inclusion complex containing two gamma-cyclodextrins and two [Cu(2-pyridinemethanolate)(2-pyridinemethanol)]PF6 units. The confinement of the molecules in the complex leads to changes in their properties. Quantum calculation reveals interfragment charge transfer. The confined copper fragment and the unincluded linear chain [Cu(2-pyridinemethanolate)(2-pyridinemethanol)]PF6 exhibit different properties.

Summary: This article presents the synthesis and characterization of a series of nickel complexes bearing a bismuth-containing pincer ligand. In particular, a 4-coordinate bismuth-nickel complex shows a sawhorse geometry, significantly distorted from a square-planar structure due to the influence of bismuth. The bimetallic cooperativity and unusual bonding properties of these complexes highlight the potential of a bismuth-nickel moiety as a new type of heterobimetallic site for the design of bimetallic complexes.

Summary: Molecular main-group hydride catalysts offer a cheap and abundant alternative to transition-metal analogues. This study demonstrates the control of electronic structure in main-group catalysts by systematically varying the ancillary ligand on the metal center. The results show that increasing electron density at the metal center leads to enhanced reactivity, and this understanding was used to develop a highly active Sn-based catalyst.

Summary: Filling carbon nanotubes with molecules is a promising approach for developing electronically modified one-dimensional hybrid structures by tuning energy levels with external parameters. Quaterthiophene molecules confined in single-walled carbon nanotubes exhibit piezo-Raman-resonance behavior, with pressure-induced enhancement of vibrational patterns. The pressure-induced nanotube radial collapse leads to an increase in resonance channels, explaining the observed piezo-resonance scenario.

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.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing. This work provides a good reference for designing fluorescent MOF probes containing CuI molecules.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
