Essay

The dissertation is devoted to direct template synthesis and structure of the 3d heterometallic complexes with ligands, which are formed by condensation of ethylenediamine, monoethanolamine and N-(2-hydroxyethyl)-ethylenediamine with acetone, methylethylketone and formaldehyde. The interaction of metal powders with amine salts and carbonyl compounds in non-aqueous solutions has been studied and heterobimetallic complexes have been obtained. The new synthetic procedures to heterometallic compounds have been elaborated and 20 novel heterobimеtallic complexes have been prepared using those. The compounds were studied by mass-, UV-Vis, IR-, NMR-spectroscopy, conductometric analysis, magnetochemistry and also tested for catalytic activity. The crystal structures of the 15 new complexes have been determined by X-Ray crystal structure analysis. It is shown, that obtained complexes can be used as components of photoconductive optical materials and as precursors for electrocatalysts of the oxygen reduction forair electrodes of chemical current sources.
