Znovjyak K. Investigation of coordination compounds of lanthanides and uranyl-ion with some СO-, PO-donor ligands

The present dissertation is devoted to exploration of the coordination and chemical properties of new compounds based on a series of carbacylamidоphosphates and their modified analogues with lanthanides and uranyl-ion in tandem with chelating ligands like 1,10-phenanthroline and 2,2'-bipyrimidine; to study of the influence of the nature of the phosphoryl ligands and of the additional neutral chelating ligands on the structure of the formed compounds, their spectral and magnetochemical properties. For the first time were synthesized and isolated two new ligands and 38 coordination compounds with lanthanides or uranyl-ion. By the monocrystal X-ray analysis were determined the modes of the coordination of the phosphoryl ligands. On the basis of the UV/vis spectroscopy was made a conclusion about similar structure of the complex species in solution and crystalline states. The results of luminescent studies of the compounds of europium allow to evaluate the setting's symmetry of the central atom. Starting from the dimethyl(1,3-thiazole-2-ylamino)carbonylamidophosphate was isolated and characterized a complex featuring non-coordinated phosphoryl group, that allows to prognose its utilization as a building block for preparation of heterometallic compounds, which can contain simultaneously rare-earth and transition 3d-elements.
