Summary: The first rare-earth metal complex bearing both hydrido- and imido-ligands, a hydrido- and imido-bridged dinuclear ytterbium(III) complex, was successfully synthesized via an unprecedented redox reaction. DFT calculation revealed that the N-2 release from azido compound in the presence of ytterbium(II) is kinetically facile due to cooperative effects. The reactivity investigation of the complex demonstrated redox, addition, and sigma-bond metathesis reactivities.

Summary: In this study, new examples of phenanthrolindiamides with asymmetric centers in amide substituents were synthesized and their structures were confirmed by spectral analysis and X-ray analysis. The synthesized ligands were found to form complexes with nitrates of rare-earth elements, and the stability constants of these complexes in acetonitrile solution were measured. Solvent extraction experiments showed that the presence of methyl groups in cyclic amide substituents significantly affected the distribution ratios and selectivity factors in the lanthanides(iii) and Am(iii) series.

Summary: A catalytic method for synthesizing a variety of cyclometalated (C^N)gold(III) complexes is reported. The unprecedented Rh-to-Au(III) transmetalation allows for the easy transfer of (C^N) ligands between the two metals in a redox-neutral process. The reaction uses commercially available precursors and proceeds under mild and environmentally friendly conditions. Experimental and computational studies support a multi-step transmetalation mechanism from rhodium to gold as the underlying process for these transformations.

Summary: In this study, several organogold(III) complexes based on 4,4 & PRIME;-diterbutylbiphenyl (C<^>C) and 2,6-bis(4-terbutylphenyl)pyridine(C<^>N<^>C) ligands were synthesized and studied. The dissociation energies of these complexes were measured using mass spectrometry and a complete methodology based on kinetic modeling and statistical methods was proposed. The results show that dissociation energy is a reliable descriptor for ligand effects and can be correlated with catalysis efficiency.

Summary: Seven new bis(mu-oxo)dimanganese complexes with Mn-2(iii,iii) or Mn-2(iii,iv) oxidation states were prepared using quinoline- and isoquinoline-based tetraamine ligands. Quinoline complexes stabilize the Mn-2(iii,iii) oxidation state, while isoquinoline ligands afford Mn-2(iii,iv) complexes. A systematic comparison of 14 complexes highlights the distinct deviation of quinoline and tripodal amine motifs in this ligand series.

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.
