Summary: The synthesized 8-bromo-4,5-bis(dimethylamino)quinoline is the simplest and first representative of quinoline proton sponges, existing in a crystalline form instead of oil. XRD study showed significant conjugation of the cyclic nitrogen atom with peri-NMe2 groups, leading to their planarization and increased distance. The mono-protonated salts of the quinoline exist exclusively in the quinolinium form. The structural index of aromaticity was calculated for the first time to compare the stability of naphthalene and quinoline proton sponges with peri-NMe2 groups. ©2023 Elsevier Ltd.

Summary: The researchers investigated the effects of Jahn-Teller elongation and compression distortions on magnetic coupling parameters by modeling a series of complex cations. They found that complexes with both elongation and compression demonstrated greater ferromagnetic interaction, attributed to the orthogonality of the magnetic orbitals and cross-interaction between certain orbitals.Constraints calculations also showed how reducing compression resulted in a decrease in magnetic coupling between Mn-III centers.

Summary: In this study, a dual cocatalyst-modified heterocatalyst strategy was employed to achieve optimal H2 evolution through ethanol photoreforming. The FeOSnS heterocatalyst with a p-n heterojunction structure was prepared, and PdOx and MnOx cocatalysts were loaded onto the FeOSnS heterocatalyst. The photocatalytic ethanol photoreforming process resulted in high selectivity for H2 production, with a synergistic redox contribution from the PdOx and MnOx species.

Summary: The four new tetranuclear Ni(II) complexes have defective dicubane cores derived from the same salicylaldoxime derived ligand. Magnetic and computational analyses revealed competitive ferro- and antiferromagnetic interactions, with differences in magnetic coupling constants due to different solvated species. Theoretical magneto-structural studies showed that the magnetic exchange interaction is highly dependent on the Ni-X-Ni angle.

Summary: This work presents studies on the photochemical transformations of TU and Cys with the addition of Cu(II) or Fe(III) ions. The results show that the oxidation rate of the thiols increases significantly when Cu(II) or Fe(III) ions are added to the system. It has also been found that TU and Cys can form stable complex compounds with the studied metal ions. The oxidation rates of the thiols are found to depend on the radiation intensity and emission spectrum of the irradiation sources.

Summary: The structure and electrochemical properties of zinc(II) complexes with a face-capping ligand have been investigated, revealing the effect of the ligand on bound semiquinonate (SQ) radicals. The substitution pattern of the SQ ring plays a crucial role in determining the fate of the bound SQ radicals. Additionally, the protective pocket formed by the ligand's phenyl substituents is unable to prevent decomposition of SQ radicals with minimal steric bulk, suggesting that substitution of the SQ ring is the main contributor to their stabilization.

Summary: In this article, the synthesis and characterization of copper, nickel, and palladium complexes bound by bidentate ligands derived from ortho-phenylenediamine are described. The complexes contain tunable H-bond donors and their crystal structures reveal intramolecular H-bonding interactions between the ligand scaffolds. Variations in the coordination sphere led to the isolation of the complexes in square-planar or twisted pseudo-tetrahedral geometries. Structural analysis showed that intramolecular H-bonding interactions can be altered by disrupting the bonds between countercations, solvent of crystallization, and ligand scaffold, resulting in changes in the geometry of the complexes. DFT calculations confirmed that Cu complexes prefer twisted geometries while Ni and Pd complexes favor square-planar geometries.
