Summary: Novel Ru(II) carbonyl and Ru(II) hydride complexes were synthesized from the reaction of 4-(2-hydroxybenzyl)-3-methyl-5-oxo-2,5-dihydro-pyrazole-1-carbothioic acid ethyl amide with RuHCl(CO)(PPh3)3. Structural evaluations were conducted using FT-IR, UV-Vis, 1H NMR and mass spectrometry. The true nature of the Ru(II) complexes was confirmed through single crystal X-ray diffraction studies and validated by DFT studies. The electrochemical properties of the synthesized complexes were studied through cyclic voltammetry.

Summary: A series of symmetrical dibenzylidene derivatives of cyclobutanone were synthesized and their structures and properties were studied using various analytical methods. The results showed that the nature, position, and number of substituents had an impact on the potential of the compounds. A linear correlation was found between the difference in oxidation and reduction potentials and the energy of the long-wavelength absorption maximum, which can be used to predict the properties of similar compounds. Quantum chemistry was used to explain the experimental findings, and the results were in agreement with the spectroscopy data and redox potentials.

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.
