On November 16, 2017 Dr. Ekaterina Bartashevich gave the lecture “Non-covalent interactions with predominant electrostatic component: halogen, chalcogen, pnictogen, tetrel bonds. Searching for electronic criteria of pnictogen bonds in nitro compounds”.Ekaterina Bartashevich – Doctor of Chemical Sciences, Professor of the Department of Theoretical and Applied Chemistry, head of the Laboratory of multiscale modeling of multicomponent functional materials of the Research and Education Center “Nanotechnologies” of South Ural State University.
Understanding the nature of chemical bonds at electronic density level and quantitative models of their properties’ description both in groups and periods of the periodic table of elements are of current importance. Recently, based on the insights into electrostatic nature, a new classification of noncovalent interactions by an atom type being an acceptor of electron density has been developed. It may be said, that every type of such noncovalent interactions corresponds to a number of compounds with physical and chemical properties that determine the utility of materials based on them. For example, pnictogen bonds between neighboring nitro groups in crystals provide close packing of electronegative groups and consequently high-energy properties. Scientific group of Dr. E. V. Bartashevich consider the development of new approaches evolving electron density distribution functions and their gradients as promising in the research and systematization of properties of halogen, chalcogen, pnictogen and tetrel bonds.
