Purpose: study of molecular and crystalline structure, as well as optical and magnetic properties of coordination compounds based on organic ligands of N-O and N-N-donor types. Research methods: NMR, electron and IR spectroscopy, ESI mass spectrometry, X-ray diffraction analysis, SQUID magnetometry. The structure of four coordination compounds based on three asymmetric polynuclear ligands was established by X-ray diffraction analysis: 2-oxymino-N '- [1- (2-pyrazyl) ethylidene] propanohydrazide, 2-oxymino-2- [1- (3,5-dimethyl) pyrazyl] - N '- (2-oxybenzylidene) acetohydrazide and 2-oxymino-N' - (2oxybenzylidene) propanohydrazide. Cryomagnetochemical studies of two polynuclear coordination compounds have been carried out and theoretical models have been developed to explain their magnetic behavior. The influence of the nature of substituents in the 5th position of 3- (2-pyridyl) -1,2,4-triazoles on the protolytic and luminescent properties of these compounds was investigated. The main regularities of interaction of Pd2 + ion with 5-substituted-3- (2-pyridyl) -1,2,4-triazoles have been established. It is shown that the complexes of Pd (TRaryl) 2 have the most promising luminescent properties. On the basis of heteropolynuclear metal-macrocyclic complex blocks of structural type 15-metal-crown-5, synthesized at the previous stage of work, and also polysulfonate ligands the technique of synthesis of three new complexes which were investigated by a number of spectroscopic methods is developed. The crystal structure of two of the synthesized compounds was established by the method of X-ray diffraction on single crystals. Product Description popup.authors Iskenderov Turganbay S.
