Abstract

Bromo-Elpasolites of formulae Cs₂LiMBr₆ and Cs₂NaMBr₆ (M = Sc, Y, La-Lu, In, V, Cr) were prepared and investigated by powder X-ray diffraction. The compounds Cs₂NaMBr₆ (M = Ce-Lu, Sc, Y, In) as well as Cs₂LiMBr₆ (M = La-Er, Y) crystallize cubic facecentered (elpasolite type of structure); Cs₂NaLaBr₆ and low temperature forms of Cs₂NaMBr₆ (M = Ce-Gd) are tetragonal. Several hexagonal crystal structure types (HT-K₂LiAlF6, Cs₂NaCrF₆, Cs₂LiGaF₆) are observed for Cs₂LiMBr₆ (M = Tm, Yb, Lu, Sc, In, V, Cr).
