摘要：
The bromides Li3MBr6 (M=Sm-Lu, Y) are obtained from the binary components LiBr and MBr3. They crystallize 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)pm, beta=109.77(6)degrees) and by powder X-ray diffraction for the remaining bromides. They are isotypic with Na3GdI6 and Li3ScCl6, respectively. Impedance spectroscopy and Li-7-NMR spectroscopy show that the lithium ions are highly mobile.
