Syntheses of Divalent Rare Earth Ternary Halides KYbBr_(3), KYbCl_(3), KSm_(2)Br_(5), KSm_(2)C_(l5), KEu_(2)C_(l5) by Alkalimetallothermoreduction

摘要

Introduction CsEuF₃, CsYbF₃ and RbYbF₃ are the first members of divalent rare earth ternary halides obtained via reduction of trivalent rare earth halides by alkali metals. Recently we adopted a new synthesis route in preparing divalent rare earth chlorides and bromides and the five titled compounds were suc-
