Symmetry reduction due to gallium substitution in the garnet Li6.43(2)Ga0.52(3)La2.67(4)Zr2O12
Single-crystal structure refinements on lithium lanthanum zirconate (LLZO; Li7La3Zr2O12) substituted with gallium were successfully carried out in the cubic symmetry space group Ioverline{4}3d. 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 Iaoverline{3}d to Ioverline{4}3d was necessary, which could hardly be analysed from X-ray powder diffraction data.
