Purpose: to correlate between the structure of polynuclear ligands N-O and N-N-donor types and the topology and properties obtained on their basis metal complexes. Research methods: NMR, electron and IR spectroscopy, ESI mass spectrometry, X-ray diffraction analysis, SQUID-magnetometry. For the synthesized palladium coordination compounds containing 3- (2-pyridyl) -1,2,4-triazole moiety, studies of their interaction with biological objects were conducted for the first time. It has been shown that the Pd (HLMe) Cl2 complex has a better cytotoxic effect than cisplatin. It was found that compounds of the type Pd (Lalk) 2 are able to act as catalysts for organic reactions of formation of the C ‒ C bond (Suzuki and Henri reactions) and can be used for several consecutive catalytic cycles without a significant decrease in activity. metal-crown-5, synthesized at the previous stage of work, and polysulfonate ligand obtained a new complex, the structure of which was established by X-ray diffraction analysis. It is established that the interaction of the heteropolynuclear complex block NoCu5 with polysulfonate ligand leads to the formation of electroneutral 1D-coordination polymer, in which No (III) ions are in the target pentagonal-bipyramidal geometry. Studies of the magnetic properties of the complex in a constant magnetic field indicate the presence of dominant antiferromagnetic exchange interactions between paramagnetic centers in metalmacrocyclic blocks {NoCu5} 3+, and the study of the dynamic magnetic properties of the compound indicate the manifestation of the properties of the molecular magnet by this complex.  Product Description popup.authors Iskanderov Turhanbai С Vashchenko Oleksandr V.
