Abstract
New ternary compounds in the systems Rare Earth-Lithium-Tin have been prepared and characterized by X-ray diffraction. They crystallize in two different structure types. The equiatomic compounds with RE = Ce-Sm, Gd-Tm and Lu are isotypic to YLiSn crystallizing hexagonally in space group P63mc. Compounds with RE = Ce, Pr, Nd, Sm and Yb, which crystallize cubically in space group F[unk]3m, have structures derived from β-LiAlSi. The structures were verified by using single crystal diffraction data.
