Summary: O-centered vanadium(IV) selenoiodide V4OSe8I6 · 3,5-dimethylpyrazole, with a tetranuclear complex [V-4(mu(4)-O)(mu-Se-2)(4)(mu-I)(2)I-4] and non-covalent contacts with iodine and selenium atoms, was synthesized at moderate temperature. The binding energies and thermal behavior of this compound, along with another similar compound, V4OSe8I6 · I2, were compared. It was found that V4OSe8I6 · I2 exhibited higher stability due to the system of non-covalent contacts involving iodine molecules.

Summary: This study investigated the effects of sub-toxic concentrations of functionalized selenium nanoparticles on prostate cancer cells and their intracellular localization and fate. The results showed that monodisperse selenium nanoparticles capped with bovine serum albumin could slow down the migration capacity of aggressive prostate cancer cells compared to polydisperse selenium nanoparticles capped with chitosan. The nanoparticles were found to interact with mitochondria in the cells. These findings provide new insight for further research on the cytotoxic mechanisms of selenium nanoparticles.

Summary: A T-shaped Pt-0 complex with a diphosphine-borane (DPB) ligand was prepared. The Pt -> B interaction enhances the electrophilicity of the metal and triggers the addition of Lewis bases to give the corresponding tetracoordinate complexes.

Summary: Reactions of bis(triphenylphosphine)dichlorometal (PPh3)(2)MCl2 (M = Ni, Pd, Pt) with trithiocarbonato anion ((BuSCS2-)-S-t) resulted in different products depending on the metal center. Nickel produced Ni(kappa S-2,S-S2CSBut)(2), palladium formed Pd(kappa S-2,S-S2CSBut)(2) and (PPh3)2Pd(kappa S-2,S-S2C = O), while platinum yielded Pt-2(mu-SBut)(2)(kappa S-2,S-S2CSBut)(2) and (PPh3)2Pt(kappa S-2,S-S2C = S). These products were characterized using various spectroscopic techniques and their crystal structures were determined by X-ray diffraction.

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.

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.
