The most significant results
Techniques have been developed for the synthesis of molecular and polymeric complexes based on 3d and 4f metal ions with carboxylic acid anions. Depending on the nature of metal ions and organic ligands between ions of heterometals, ferromagnetic type of exchange interactions is realized, or aromatic fragments sensitize the bright luminescence of lanthanide ions.
Methods for the synthesis of Li-M (M = V4 +, Co2 +, Ni2 +, Cu2 +, Zn2 +) tetranuclear molecular complexes have been developed. Using the example of the Li-Zn complex, it was shown that the {Li2M2 (O2C) 6} fragment is a new type of secondary block for the synthesis of new organometallic frameworks (MOFs) (in conjunction with the Institute of Organic Chemistry of the Siberian Branch of the Russian Academy of Sciences).
It was shown that the combination of the dianion bichelate fragment {M (R2mal) 2} 2- (M = V4 +, Co2 +, Ni2 +, Cu2 +, Zn2 +) and the heterometallic cation (alkali, alkaline earth, transition metals) or organic cation forms molecular, including compounds with the nucleus M36 (M = Co, Ni), and polymer complexes of various topologies.
The molecular assembly method based on the {Fe2MO (Piv) 6} blocks (M = Co, Ni) and bi- and tridentate bridging N-donor ligands yielded hard and breathing porous coordination polymers (together with the Institute of Physics and Technology, National Academy of Sciences of Ukraine).
