Chebanenko E. Synthesis, structure, and properties of the products of complex formation of germanium and tin tetrachlorides with citric, tartaric and xylaric acids

The thesis is devoted to the formation and establishment of patterns in the chain compound - structure - functional properties of homo-and heteropolynuclear hydroxycarboxylategermanates(stannates). The X-ray crystal structure analysis of 17 compounds has been carried out. For the first time, on the basis of synthesis and investigation of the structure of 28 new homo-and heteronuclear hydroxycarboxylategermanates (stannates) with s-, d-metals, features of complex formation of germanium, tin tetrachlorides with citric, tartaric, xylaric acids are identified, depending on the nature of the solvent (water, acetic acid, acetonitrile), the number and combination of complex-forming conditions of the experiment. The high capacity of the synthesized hydroxyacidic complexes of germanium and tin is exposed to show pharmacological, biological and catalytic activity.
