Copper(II) complexes of a novel pyrazole containing porphyrinogen and cobalt(III) and zinc(II) complexes of a pyrazole containing tripodal ligand having N-donor atoms have been investigated. 5-Methyl-3-formylpyrazole (MPA) on reaction with copper(II) nitrate or perchlorate in the presence of tris(2-aminoethyl)amine (tren) forms novel pyrazole-based porphyrinogen complexes [Cu(T(3)-porphyrinogen...

The asymmetric unit of the title compound, [Co(NO3)2L] n , L = N-(pyridine-2-ylmeth-yl)pyridine-3-amine (C11H11N3), contains one CoII centre, two nitrate anions and one L ligand in which the Cpy-C-N-Cpy moiety adopts a trans conformation with a torsion angle of -173.1 (3) Å. The coordination geometry of the CoII atom is a distorted penta-gonal bipyramid. One amine N atom from the L ligand and f...

A synthetic growth medium was purified with the chelator 1,5-diphenylthiocarbazone to study the effects of copper on partial reactions and product formation of nitrite respiration in Pseudomonas perfectomarinus. This organism grew anaerobically in a copper-deficient medium with nitrate or nitrite as the terminal electron acceptor. Copper-deficient cells had high activity for reduction of nitrat...

Abstract Ammonium nitrate is a hygroscopic and caking product for growing agricultural products. In order to improve the properties of ammonium nitrate, composition calcined crushed cathode material from used lithium ion battery was studied. Since mainly consists lithium, cobalt, manganese nickel, it has been adopted as polymicroelement-containing additive nitrate. Studies have shown that intro...

For the synthesis of Cobalt Nanoparticles (CoNPs), prudent wet phase reduction process was applied by employing urea as an effective oxidizing agent. The requirement analogous precipitation executed method fulfilled taking advantage sufficiently slow hydrolysis in water at acceptable temperature. experiment carried out mixing cobalt nitrate and (1:2) distilled water. reaction mass then subjecte...
