Summary: The study found that the [S-BAr4F](-) anion enhances the stability of the sigma-alkane complex [Rh(Cy2PCH2CH2PCy2)(norbornane)][S-BAr4F] both thermally and when suspended in pentane. Furthermore, the increased stability of [S-BAr4F](-) salts is mainly attributed to enhanced non-covalent interactions in the lattice.

Summary: The reactivity of 2,3-pyridine-dicarboxylic and 2,5-pyridine-dicarboxylic acids as ligands towards the niobium(IV) tetrachloride precursor was studied, resulting in the formation of four crystalline mononuclear coordination complexes with different molecular arrangements. Each complex showed an eightfold coordination of the niobium(IV) center and exhibited unique structural characteristics. Magnetic measurements, EPR and XPS were used to analyze the d(1) configuration of the niobium(IV) centers, revealing an anti-ferromagnetism transition at very low temperatures for certain complexes.

Summary: This study demonstrates a strategy for synthesizing high-mobility semiconducting coordination polymers (c-CPs) using novel conjugated ligands with reduced symmetry. The synthesized c-CPs exhibit a small band gap, dispersive energy bands, and high charge carrier mobilities, outperforming previously reported conductive coordination polymers. This molecular design strategy lays the foundation for achieving high-performance c-CP-based (opto-)electronics.

Summary: In this study, a strategy for synthesizing high-mobility semiconducting conjugated coordination polymers (c-CPs) using novel conjugated ligands with D2h symmetry was demonstrated. The reduced symmetry of the 4 + 2 ligands compared to conventional phenyl ligands led to anisotropic coordination in the formation of c-CPs. A single-crystalline three-dimensional (3D) c-CP Cu4DHTTB with orthogonal ribbon-like pi-d conjugated chains was successfully achieved. This c-CP exhibited a small band gap, dispersive energy bands, and high charge carrier mobilities, laying the foundation for high-performance c-CP-based (opto-)electronics.

Summary: The use of DESs as replacements for traditional solvents in the recovery process of lithium-ion batteries has been widely reported. This study proposes a DES modified by reducing agents, which overcomes the challenges faced by previous research, such as high viscosity, poor reuse performance, and operation conditions. The DES of GUC and LAC with 1 wt% ascorbic acid can dissolve nearly 100% of LCO and NCMs under mild conditions. After stripping Co and supplementing VC, the modified DES can maintain its dissolution properties for at least three cycles. The acidity and reducibility of the DES were also measured as key factors for the dissolution of Li and Co.

Summary: The separation of actinides from lanthanides is a crucial step in the spent nuclear fuel reprocessing. Organophosphorus extractants, such as tributyl phosphate (TBP) and octyl(phenyl)-N,N-diisobutylcarbamoylmethylphosphine oxide (CMPO), have been widely used due to their strong extraction ability and low cost. This article discusses the application scope, extraction mechanism, structure-function relationships, and newly developed organophosphorus extractants for the separation of actinides over lanthanides. The important role of these extractants and their potential applications in future advanced nuclear fuel cycle are also emphasized.

Summary: In this study, the extraction effect and complexation mechanism of C2-POPhen and C4-POPhen with the high-valence actinides U(VI) and Th(IV) were systematically investigated. It was found that the POPhen extractants exhibited excellent coordination and extraction ability for U(VI) and Th(IV) under highly acidic nitrate conditions. C4-POPhen showed stronger extraction capacity compared to C2-POPhen, and both ligands had a stronger extraction capacity for Th(IV) than U(VI) under the same experimental conditions. The study also revealed the formation of 1:1 and 1:2 metal-to-ligand complexes between POPhen extractants and Th(IV) through slope analysis and spectroscopic studies, and the structures of these complexes were elucidated by X-ray crystallography. This study provides valuable insights into the extraction effect and complexation mechanism of POPhen extractants with high-valence actinide elements and serves as a basis for the development of advanced actinide separation processes.
