The structure described by LiErO2 crystallizes in the tetragonal I4_1/amd space group. Li(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Er(1) is bonded to six equivalent O(1) atoms to form a mixture of edge and corner-sharing ErO6 octahedra. The corner-sharing octahedral tilt angles are 15°. O(1) is bonded to two equivalent Li(1) and three equivalent Er(1) atoms to form a mixture of edge and corner-sharing OLi2Er3 square pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
