Summary: A novel N-methyl substituted, radical anionic complex [Ni(Me-thiazSe-dt)(2)](1-) is synthesized by combining the N-R substitution found in [Ni(R-thiazdt)(2)] complexes and the selone substitution found in [Ni(dmiSe)(2)] complex. This anionic complex and its mixed-valence Et4N+ salt exhibit a rare cis arrangement of the dithiolene ligands and form well-isolated dimerized chains in the 1 : 2 [Et4N][Ni(Me-thiazSe-dt)(2)](2) salt, showing strong one-dimensional character. Despite its Mott insulator behavior, the compound retains high RT conductivity of 4.6 S cm(-1) and small activation energy of 33 meV under pressures up to 10 GPa.

Summary: This study investigates the optical properties of octahedral molybdenum cluster complexes, identifying the influence of crystal packing and ligand environment on their absorption and emission properties. The research also determines the four-component nature of cluster emission through Gaussian deconvolution of photoluminescence spectra. It is found that the impact of ligand type and crystal density decreases as the spectra move to the lower-energy red part, with protonation of hydroxo ligands significantly reducing absorption in the visible spectral region.

Summary: In this study, an efficient tungsten-catalyzed homogeneous system was developed for the selective synthesis of various azoaromatics, azoxyaromatics, and 2-substituted indolone N-oxides from anilines. This was achieved by regulating the reaction solvent with peroxide as a terminal oxidant under additive-free conditions. These findings not only provide an experimental framework for exploring tungsten catalysis in organic synthesis but also offer an efficient and convenient tactic for the selective oxidation of anilines.

Summary: This paper presents the synthesis, characterization, and biological properties studies of a series of 5 coordination compounds based on binuclear core [Mo(V)2O2S2]2+ with thiosemicarbazones ligands bearing different substituents. The structures of the complexes in solution are determined using MALDI-TOF mass spectrometry and NMR spectroscopy, and compared to single-crystal X-Ray diffraction data. The antifungal and antioxidative activities are explored and the coordination compounds show higher potential compared to the uncoordinated ligands. DFT calculation provides support to the solution studies and explains the antioxidative properties of these systems by determining the most stable isomers and HUMO and LUMO levels.

Summary: The possibility of Dirac cone formation in two single-component molecular conductors derived from nickel complexes with extended tetrathiafulvalenedithiolate ligands was investigated using tight-binding models and first-principles density-functional theory (DFT) calculations. Both the tight-binding model and DFT calculations predicted the emergence of Dirac cones in both systems, which is associated with the stretcher bond type molecular arrangement. DFT calculations confirmed the formation of Dirac cones near the Fermi level in the nonmagnetic state after structural optimization in [Ni(btdt)(2)]. Furthermore, DFT calculations also confirmed the antiferromagnetic stability in [Ni(btdt)(2)].

Summary: We have provided experimental evidence for the orbital degrees of freedom in anion-radical salts containing metal-dithiolene complexes. By analyzing the NIR absorption spectra of Me4Q[Pt(dmit)2]2 (Q = N, P, and Sb), we observed a phase transition from metallic to semiconducting and charge-ordered phase. Our results showed that the highest-energy electrons occupy bonding orbitals in the charge-ordered phase and antibonding orbitals in the metallic phase. Furthermore, we found that the redistribution of charges and replacement of outermost orbitals occur in all dimers of Me4Q[Pt(dmit)2]2.

Summary: HP's Multi Jet Fusion is a 3D printing technology that uses a carbon-based radiation absorber and a near infrared light source to fuse polymer powder in layers and create 3D parts. To generate white, bright colored, and translucent parts, a visibly transparent and colorless radiation absorber is needed. The authors designed an activating fusing agent with a red, strong NIR absorbing dye that turns colorless after absorbing radiation energy during the 3D printing process, allowing for the creation of bright colored parts when used with other color agents.

Summary: Catalyzed by a Mo-3(mu(3)-S)(mu-S)(3) diamino complex, azobenzene hydrogenation occurs under moderate conditions through a cluster catalysis mechanism. Dihydrogen activation takes place at the mu-S bridging atoms without direct participation of the metals, leading to the formation of an intermediate with similar appearance and disappearance rate constants. The experimental results support the proposed mechanism, demonstrating the potential of molybdenum sulfide materials as catalysts in hydrogenation processes.

Summary: By using a cuboidal [Mo3S4H3(dmpe)(3)](+) hydride cluster as the catalyst, formic acid (FA) can be transformed into hydrogen gas and CO2 without the need for any additives. Compared to other molybdenum compounds, our catalyst has shown higher activity and selectivity. Kinetic studies, reaction monitoring, and DFT calculations have revealed the mechanism of FA dehydrogenation, which involves the formation of a dihydrogen-bonded species and subsequent release of hydrogen gas and coordination of formate. The complete cycle, including the release of CO2 and closure of the catalytic cycle, occurs at higher temperatures.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
