Summary: Four new structurally similar dinuclear oxorhenium(V) complexes have been synthesized and characterized, showing little variation in spectroscopic features. All complexes exhibit a bent Re-O-Re core and distorted octahedral coordination geometry. A reversible one-electron electrochemical process is observed at approximately 0.84 V vs. Fc(+)/Fc in all four complexes, with a slight destabilization of the oxidized Re(VI) center when changing the terminal halide from chloride to bromide.

Summary: In the past decade, N-heterocyclic carbene, bipyridine, and pyridine oxazoline ligands have been increasingly used in nickel catalysis. The combination of a low-oxidation-state 3d metal and an electron-rich ligand allows for challenging bond activations. This study reports the synthesis and characterization of two Ni(0) complexes supported by a novel bidentate C,N ligand, (h)IMesPy, which shows potential for overcoming reactivity challenges.

Summary: The complexation behavior between a calix[4]arene ligand H3L2 with a pendant picolyl-imine arm and lanthanide ions has been investigated, resulting in dimeric neutral complexes. The dimeric species were also found in CH2Cl2/MeOH and MeCN solutions. Additionally, the appended picolyl-imines can sensitize Eu-III and Tb-III emissions in the solid state or immersed in a PMMA matrix.

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: Isomorphous series are generated by replacing atoms or molecules to form materials with similar compositions. They allow modulation of structure and properties, and generate equivalent compositions with novel material properties. The study of stereo-electronic aspects of different equivalent compositions can improve the utility of the original composition.

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.

Summary: Three BODIPY-Ru(II) complexes were synthesized by coordinating [Ru(bpy)2Cl]+ complexes to BODIPY ligands. The spectroscopic and electrochemical properties of the complexes were characterized. The complexes exhibited intense absorption peaks due to the pi pi* transitions localized on the BODIPY core, and additional charge transfer transitions associated with the metal center. The complexes showed significant singlet oxygen generation and were able to induce photo-nicking of DNA.
