Summary: In this study, mixed-ligand lead(II) complexes with 2,2'-bipyridyl and [B10H9OH](2-) or monosubstituted hydroxy-substituted closo-decaborate anions with a pendant hydroxy group were synthesized and characterized by IR and multinuclear NMR spectroscopies. The structures of a binuclear complex [Pb(bipy)(2)[B10H9OH]](2)·CH3CN, a mononuclear complex [Pb(bipy)(2)[B10H9O(CH2)2O(CH2)2OH]]·0.5bipy·CH3CN, and a polymeric complex [Pb(bipy)[B10H9O(CH2)5O(CH2)2OH]](n) were determined by single-crystal X-ray diffraction. The coordination polyhedra of lead(II) in these compounds are formed by N atoms from bipy molecules, O atoms of the substituents, and BH groups of the boron cage.

Summary: A method has been developed for obtaining perchlorinated di-S,S-substituted derivatives of the closo-decaborate anion with various alkyl groups. The process involves alkylation of the anion with bromoalkanes followed by cluster chlorination with sulfuryl chloride in acetonitrile, resulting in complete replacement of hydrogen atoms with chlorine within 60 hours. The melting point of the salts strongly depends on the length of the hydrocarbon chain of the substituent R.

Summary: Nanocrystalline cobalt monoboride was synthesized by thermal decomposition of precursors [Co(DMF)(6)][An], where [An] = [B12H12](2-) (1), [trans-B20H18](2-) (2) or [B10Cl10](2-) (3) in an argon atmosphere. Three new salt-like compounds 1-3 were obtained by the reaction of Co(NO3)(2) with (Et3NH)(2)[An]. Characterization of the annealed products 1a-3a revealed the presence of BN and CoB for 1a, a higher CoB:BN ratio for 2a with decreased crystallinity, and only CoB for 3a. TEM analysis showed that 1a and 2a had small particle sizes (10-15 nm) and a normal size distribution, while 3a had large particles (200-350 nm) with a broad distribution.

Summary: This study describes and fully characterizes novel selenodiazolium salts derived from the reaction between 2-pyridylselenyl reagents and cyanamides. Eight adducts were studied by single crystal structural analysis, which revealed the presence of four-center N-Se interactions for some of them with an estimated interaction energy of -3.9 kcal mol(-1), as revealed by theoretical calculations. The reaction mechanism between nitriles of the general formulae RC=N (R = Me, Ph, Br, CCl3, Me2N, Ph(H)N) and 2-pyridylchalcogenyl halides 2-PyChX (Ch = Se, Te; X = Cl, Br) was also investigated by theoretical methods, suggesting the asynchronous cycloaddition nature of the process.

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.
