Abstract:

Schiff base readily form complex with metal ions and the resultant complexes especially from transition metals were extensively used in many fields of human endeavor including antimicrobial therapy. However, the potentials of Lanthanide-Schiff base complexes as an antimicrobial agent have not been adequately studied. This study aims to synthesize and determine the antimicrobial activity of Bis-salicylaldehyde ethylenediamine Schiff Base and its Lanthanoids (III) Complexes. The Dysprosium (III), Gadolinium (III), Neodymium (III) and Samarium (III) complexes of Schiff base derived from Salicylal

The paper gains a new method for the synthesis of γ-MnOOH crystals by adding ethylenediamine metal complexes under hydrothermal conditions. Study the effect of different preparation process to the reaction products .The structure and morphology of the resultant products were characterized by using XRD, SEM. The results show that the product is α-MnO2 when did not join the ethylenediamine metal complexes and the product is γ-MnOOH when joined the ethylenediamine metal complexes in 100°C under hydrothermal conditions. The purity of the γ-MnOOH is not the same when adding different ethylenediamin

Abstract:

The presence of iodine and iodide ions in tetracyanonickelates inclusion compounds with the general formula Ni(B)mNi(CN)4 . n H2O (B = NH3 or ethylenediamine) changes the properties of these compounds. High frequency conductance measurements in the range of 10 - 105 Hz show that the products with ethylenediamine ligands have a higher electrical conductivity than those with NH3 ligands. The differences in the electrical properties between the compounds studied are mainly caused by chemical composition, structure and morphology.

Abstract:

Condensation reactions involving various ketones and amines formed noncyclic ligands denoted as LI, LII, LIII, and LIV. Ethylenediamine, when reacted with acetophenone, benzoylacetone (in the presence of 70% HClO4), and benzophenone, resulted in the following noncyclic ligands: (E,E)-N,N-bis(1-phenylethylidene)ethylenediamine (LI), bis(1-3-hydroxy-3-phenylbut-2-ene-ylidene) (LII) and (E,E)-N,N-bis(1,1-diphenylmethylidene)ethylenediamine (LIII), respectively. The reaction of benzophenone with 1,3-diaminopropane in a 1:1 ratio in a methanolic solution also led to the synthesis of a noncyclic lig

A series of new hetero binuclear complexes of copper(II) and lead(II) using Schiff base have been synthesized. The Schiff base has been derived from the condensation reaction between Salicylaldehyde and 1,2-Ethylenediamine.

Abstract:

CO2 methanation was studied in the presence of nickel catalysts obtained by the solid-state combustion method. Complexes with a varying number of ethylenediamine molecules in the coordination sphere of nickel were chosen as the precursors of the active component of the catalysts. Their synthesis was carried out without the use of solvents, which made it possible to avoid the stages of their separation from the solution and the utilization of waste liquids. The composition and structure of the synthesized complexes were confirmed by elemental analysis, IR spectroscopy, powder XRD and XPS method

The reduction of [Co(en)3]3+ into [Co(en)3]2+ was shown to be totally irreversible, one-electron exchange reaction. Further reduction of [Co(en)3]2+ was found to be com

The complexes were synthesized by the reaction of chromium(III) chloride, S,S-eddp and malonic acid or sodium oxalate, at 60?C. The complexes were isolated chromatographically and the geometric configuration of the complexes was proposed on the basis of their infrared and electronic absorption spectra.
