Abstract

We have identified linear correlations between the molecular refractions R mol (cm3/mol) of crystals and the ionic radii r i (Å) of the cations in the RF3 rare-earth trifluoride homologous series: R mol = 8.33r i + 0.102 for R = La–Nd and R mol = 13.03r i–4.42 for R = Sm–Lu. The fact that the RF3 rare-earth trifluorides can be divided into two groups is related to the morphotropic transition from the LaF3 (tysonite) structure to the β-YF3 structure. The correlation found here for RF3 crystals with the β-YF3 structure because the electronic structure of Y (4d 15s 2) differs from that of Sm–Lu (4f 6–145d 0–16s 2) in that it has no 4f electrons.
