An X-ray powder diffraction study of the chloride-bromide systems of trivalent gadolinium, terbium, and ytterbium

Compound-tunable embedding potential method: analysis of pseudopotentials for Yb in YbF2, YbF3, YbCl2 and YbCl3 crystals

“…of YbF 3 and YbCl 3 crystals, our calculations confirm those crystal structures that are described in ref. 27 and 35-37, but not in earlier studies [41][42][43][44][45] of the ytterbium trihalides. Thus, theoretical studies of the crystals can help to resolve inconsistency in experimental data.…”

“…38-40. The next example is YbCl 3 , for which the lattice parameters in a recent paper 27 are quite different from those of earlier studies. [41][42][43][44][45] Thereby, their accurate theoretical study could help to clarify the situation.…”
