The complex-forming ability of 2-methyl-3-hydroxypyran-4-one (1a), 2-ethyl-3-hydroxypyran-4-one (1b), 1,2-dimethyl-3-hydroxypyridin-4-one (4a) and 1-ethyl-2-methyl-3-hydroxypyridin-4-one (4b) with nickel(Ni(II)) were characterized by infrared, ultraviolet, proton nuclear magnetic resonance spectroscopy and melting point. The mole-ratio of nickel:ligands was analyzed by atomic-absorption-spectro...

ni6(n2h4)6(so4)4(oh)2(h2o)8](so4)(h2o)10 complex was prepared according to literature report. the reaction between aforementioned complex via sodium alkoxides as a reactants, were carried out in the solid state. the [ni6(n2h4)6(so4)4(oh)2(h2o)8](so4)(h2o)10 undergoes an intramolecular two electrons oxidation-reduction reaction at room temperature and metallic nickel nanoparticles (ni1-ni5) was ...

We report a seed-mediated hydrothermal growth of free-standing nickel hydroxide [Ni(OH)(2)] and nickel oxide (NiO) nanoflake arrays and their implementation as electrodes for non-enzymatic glucose sensors. Ni(OH)(2) nanoflakes were converted into porous NiO nanoflakes upon thermal annealing in air at temperatures of 300 °C or above. NiO nanoflake-arrayed sensors achieve an excellent glucose sen...

An extremely bent cyanide coordination at a dinickel scaffold is reported. Preorganization of two nickel ions is achieved by means of a compartmental dinucleating pyrazolate ligand L(-), setting up a bimetallic coordination pocket with constrained metal-metal separation. The mixed-spin dinickel(II) complex [LNi2(CN)(MeCN)](ClO4)2 (1) has been characterized by X-ray diffraction. The MeCN bound t...

This study addressed the design and syntheses of diverse ligands, which were then successfully treated with Ni (II) ion to afford a series of nickel complexes. α-Chloroformylarylhydrazine hydrochlorides contain two different functional groups. One is a strong nucleophile, and the other is a good electrophile. Therefore, it can be designed to react with several reagents to obtain diverse derivat...

The solubility of NiO(cr) was measured using flow techniques and a potentiometric method from ca. 0 to 350°C in aqueous solutions as a function of pH. A more limited study of the solubility of -Ni(OH)2(cr) was conducted by both techniques to 200°C. These results indicate that the transition temperature at which nickel hydroxide dehydrates to form the oxide is ca. 75°C, much lower than previousl...

Investigations of chemical bonding and electronic structure features for polycrystalline (porphyrinato)nickel (II) (NiP, the simplest Ni porphyrin), (5,10,15,20-tetraphenylporphyrinato)nickel (II) (NiTPP) and (2-aza-21-carba-5,10,15,20-tetraphenylporphyrinato)nickel (II) (N-confused NiTPP, NiNCTPP) have been performed by means of high-resolution soft x-ray absorption and x-ray photoemission spe...
