It is shown that the experimentally observed tendencies in the change in the oxoniobate stability correlate with the decrease in the average electron–proton binding energy of LnO8 clusters and enhanced repulsion between Ln and O orbitals to the end of the lanthanide series Доп.точки доступа: Reznitskikh, O.
