Purpose: development of synthetic approaches for obtaining mono- and polynuclear coordination compounds of transition and rare earth metals with organic ligands of N-O and N-N-donor types. Research methods: NMR, electron and IR spectroscopy, ESI mass spectrometry, X-ray diffraction analysis. For the first time, the coordination and chemical properties of 2-oximino-N '- [1- (2-pyrazyl) ethylidene] propanohydrazide were systematically investigated. Optimal conditions for the formation of discrete mono- and polynuclear complexes on its basis in methanol and water-methanol solutions have been established. Coordination and chemical properties of picolin and quinolinhydroxamic acids have been systematically investigated. Eighteen new palladium (II) coordination compounds were obtained and characterized on the basis of 10 substituted 3- (2-pyridyl) -1,2,4-triazoles, 7 of which were synthesized for the first time. The molecular and crystalline structure of 9 palladium complexes was established by X-ray diffraction analysis. For the first time, systematic studies of the influence of axial ligands on the structural characteristics of 15-MC-5 have been performed, the dominant influence of the nature and type of axial coordination on the conformation of a metal cycle and the deviation of the encapsulated ion from its plane have been demonstrated. The method of synthesis of heteropolyaderic complexes of structural type 15-metal-crown-5 was modified, on the basis of which four new complexes containing metal-macrocyclic skeletons {LnCu5} 3+ (Ln3 + = Gd, Tb, Dy, Ho) were obtained. It has been established that the government of metal-macrocyclic complexes is experiencing a decrease in some crystal lattice parameters and bond lengths due to the effect of lanthanide compression.  Product Description popup.authors Iskenderov Turganbay S.
