The crystal structure described by LiTmO2 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. Tm(1) is bonded to six equivalent O(1) atoms to form a mixture of edge and corner-sharing TmO6 octahedra. The corner-sharing octahedral tilt angles are 14°. O(1) is bonded to two equivalent Li(1) and three equivalent Tm(1) atoms to form a mixture of edge and corner-sharing OLi2Tm3 square pyramids. is represented by the CIF card [CIF]
