Abstract: The bromides Li3MBr6 (M = Sm - Lu, Y) are obtained from the binary components LiBr and MBr3. They are crystallized with a substitution/addition variant of the AlCl3-type of structure as was established from single crystal X-ray diffraction data for Li3ErBr6 (monoclinic, C2/m, Z = 2, a = 689.0(3), b = 1191.6(9), c= 684.2(6), b = 109.77(6)) and by powder X-ray diffraction for the remaining bromides. They are isotypic with Na3GdI6 and Li3ScCl6, respectively. Impedance spectroscopy and 7Li-NMR spectroscopy show that the lithium ions are highly mobile.
