Abstract:The Li3MX6 compounds (M = Sc, Y, In; X = Cl, Br) are known as promising ionic conductors due to their compatibility with typical metal oxide cathode materials. In this study, we have successfully synthesized γ‐Li3ScCl6 using high pressure for the first time in this family. Structural analysis revealed that the high‐pressure polymorph crystallizes in the polar and chiral space group P63mc with hexagonal close‐packing (hcp) of anions, unlike the ambient‐pressure a‐Li3ScCl6 and its spinel analog with cubic closed… Show more
