Karazin Kharkiv National University popup.description2 Research methods - electrosynthesis, X-ray diffraction analysis, resistive measurements, spin formalism of the valence bond method, analytical methods of quantum solid state theory. For the first time, cation-radical salts (TMTTF) [3,3'-Cr (1,2-C 2 B 9 H 10 ) 2 ], (TMTTF) (3,3'-Fe (1,2-C 2 B 9 H 10 ) 2 ] and (TMTSF) 2 [3,3’-Cr(1,2-C 2 B 9 H 10 ) 2 ] were synthesized by electrocrystallization. Тheir structure and conductive properties were studied. Sorption material based on hydrolyzed lignin modified with 30% of MnO (OH) particles was synthesized for the first time. Frustrated spin models of periodic chain magnets were proposed, which do not have a gap in the energy spectrum even in the case of an even number of spins per unit cell. A technique is proposed that allows to systematically design magnets with given properties of the lower part of the energy spectrum in the approximation of linear spin waves and magnetic nanoclusters with similar values of the lower part of the exact energy spectrum.
