CaSm2O4 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 Sm(1)O6 octahedra. The corner-sharing octahedral tilt angles are 59°. Sm(1) is bonded to six equivalent O(1) atoms to form SmO6 octahedra that share corners with six equivalent Ca(1)O4 tetrahedra and edges with six equivalent Sm(1)O6 octahedra. O(1) is bonded to one Ca(1) and three equivalent Sm(1) atoms to form a mixture of distorted corner and edge-sharing OCaSm3 trigonal pyramids.
