Abstract
Systems analysis of available data on the thermodynamic properties of binary lanthanide hydrides is carried out. The standard thermodynamic characteristics of lanthanide dihydrides (Δf H o, S o, C op ) and their hypothetical trihydrides (Δf H o) are calculated. The calculations are performed using a semiempirical method that takes into account the effects of the number of f-shell electrons and the spin and orbital angular moments of ground states of the lanthanide ions on the thermodynamic properties of the compounds studied. It is established that the thermodynamic characteristics of the hydrides exhibit an antibatic behavior with respect to the atomic numbers of the natural series lanthanides. The tetrad effect was revealed for these series of compounds.
