LiErO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Li(1) is bonded to six equivalent O(1) atoms to form LiO6 octahedra that share corners with six equivalent Li(1)O6 octahedra and faces with eight equivalent Er(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Er(1) is bonded to twelve equivalent O(1) atoms to form ErO12 cuboctahedra that share corners with twelve equivalent Er(1)O12 cuboctahedra, faces with six equivalent Er(1)O12 cuboctahedra, and faces with eight equivalent Li(1)O6 octahedra. O(1) is bonded in a distorted linear geometry to two equivalent Li(1) and four equivalent Er(1) atoms.
