Abstract
New ternary compounds in the systems Rare Earth-Lithium-Tin have been prepared and characterized by X-ray diffraction. They crystallize in t wo different structure types. The equiatomic compounds with RE = Ce-Sm , Gd-Tm and Lu are isotypic to YLiSn crystallizing hexagonally in spac e group P6(3)mc. Compounds with RE = Ce, Pr, Nd, Sm and Yb, which crys tallize cubically in space group F43mBAR, have structures derived from beta-LiAlSi. The structures were verified by using single crystal dif fraction data.
