CaTm2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Ca(1) is bonded to four equivalent O(1) atoms to form CaO4 tetrahedra that share corners with twelve equivalent Tm(1)O6 octahedra. The corner-sharing octahedral tilt angles are 60°. Tm(1) is bonded to six equivalent O(1) atoms to form TmO6 octahedra that share corners with six equivalent Ca(1)O4 tetrahedra and edges with six equivalent Tm(1)O6 octahedra. O(1) is bonded to one Ca(1) and three equivalent Tm(1) atoms to form a mixture of distorted edge and corner-sharing OCaTm3 tetrahedra.
