Structural changes in series of LnFeO3 and LnF3
Description
Structural analogy of two classes of rare-earth compounds, fluorides LnF3 (Ln=Sm-Lu) and oxides LnFeO3 (Ln=Pr-Lu), has been established. Reduction of the coordination number of the Ln3+ cation in these compounds occurs due to displacement of O or F atoms, leading to an increase in certain cation-anion distances. Anisotropy in the change of individual interatomic distances determines non-monotonicity of the curve of parameters of the crystal lattice in the series LnF3 and LnFeO3
