Karazin Kharkiv National University popup.description2  The purpose of the work: experimental and theoretical research of low-dimensional coordination compounds of transition metals, ion-radical salts of organic complexons of heterocumulene and related types, as well as graphene nanoclusters with embedded heteroatoms with the aim of further creating the newest multifunctional materials based on them; search for new effective adsorbents for the removal of radionuclides from environmental objects based on the compounds under study. For the first time, radical cation 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 ], their structure and conductive properties were investigated. New coordination compounds of Copper (II) and Cobalt(II) were synthesized and their crystal structure was investigated. Frustrated spin models of periodic chain magnets are proposed, which do not have a gap in the energy spectrum even in the case of an even number of spins per unit cell. Using the renormalization group method in the formalism of the density matrix and the quantum Monte Carlo method, the existence of an intermediate plateau in the magnetization profile of composites based on graphene clusters and complex compounds of transition metals is shown.
