- Аннотация: Different correlations between the various physical and chemical properties of isostructural compounds take place according to the Periodic Table that is a fundamental basis of Chemistry. The systematization of this approach, data vs. the Periodic Table, will contribute to further development of the solid state chemistry theory. In this paper, we analyze some classes of compounds formed by the lanthanides with other elements of the Periodic Table, which can count into the thousands of binary compounds. The special place of lanthanides in the Periodic System of Elements made it possible to establish strict nonlinear correlations between the standard entropy and the lanthanide atomic number the compounds Ln2X3 (X=O, S, Se, Te), LnN, LnB4, and LnF3 in the solid state. These correlations can be applied to other physical and chemical properties of isostructural compounds. This tetrad-effect concept is an effective tool to predict missing thermodynamic values for lanthanide compounds and to rationally plan experiments.
