PETRO-BOGDAN KRYPYAKEVYCH: FOUNDATION OF LVIV SCIENTIFIC SCHOOL ON CRYSTAL CHEMISTRY

The Scientific School “Crystal Chemistry”, which is established at the Department of Inorganic Chemistry at the Ivan Franko National University of Lviv, is well-known all over the world for their contributions in the field of crystal chemistry of intermetallic compounds. The activities cover studies of the interaction of components in metallic systems, phase diagrams, crystal structures, chemical and physical properties, and applications. The School was founded 60 years ago, by Evgen Cherkashyn, Evgen Gladyshevskii, and Petro-Bogdan Krypyakevych. Since the foundation of the School, scientists have investigated interactions involving more than 70 different chemical elements in about 3,000 multicomponent systems: constructed isothermal sections of the phase diagrams of 1,400 systems, confirmed or revealed the formation and determined the crystal structures of 6,700 compounds, and discovered 520 new structure types. The analysis of the large amount of experimental material and various theoretical data on the crystal structures of intermetallic compounds made it possible to deduce a number of important crystal chemical regularities among intermetallic compounds. Petro-Bogdan Krypyakevych proposed a universally recognized method to systematize the structure types of intermetallic compounds based on the coordination of the atoms, which is included in the International Historical Atlas of Crystallography. Evgen Gladyshevskii and his successor Oksana Bodak systematized the relationships between structure types and the transformations of one type into another. Other members extended the work to other classes of compounds: Maryan Myskiv formed a direction on crystal chemistry of complex compounds of copper(I) halides with organic ligands, Volodymyr Pavlyuk initiated research on hydrides – hydrogen accumulators, and Roman Gladyshevskii, in addition to contributing to the systematization of structure types of inorganic compounds, extended the research to superconducting oxides with high critical temperature. The contributions of Lviv Scientific School on Crystal Chemistry can be estimated to 20 % of the world achievements in the field of crystal chemistry of intermetallic compounds. The total number of scientific publications of the department reached 5,500 in 2023, including 56 monographs and handbooks. Scientists of the School are also the coauthors of 153 copyright certificates and patents. Under the scientific direction of the School, 191 doctors in chemical sciences (165 Ph.D., 26 Prof.) have been formed, and eleven members of the School are laureates of the State Prize of Ukraine in the field of science and technology.

Keywords: : crystal chemistry, inorganic chemistry, materials science, crystal structure, structure type, scientific school.
