Abstract
Single-crystal structure refinements on lithium lanthanum zirconate (LLZO;
Li7La3Zr2O12) substituted with gallium were successfully carried out in the cubic
symmetry space group I43d. Gallium was found on two lithium sites as well as on
the lanthanum position. Due to the structural distortion of the resulting
Li6.43(2)Ga0.52(3)La2.67(4)Zr2O12 (Ga–LLZO) single crystals, a reduction of the
LLZO cubic garnet symmetry from Ia3d to I43d was necessary, which could
hardly be analysed from X-ray powder diffraction data.
