The material structure described by SrSm2O4 is Spinel structured and crystallizes in the cubic Fd-3m space group. Sr(1) is bonded to four equivalent O(1) atoms to form SrO4 tetrahedra that share corners with twelve equivalent Sm(1)O6 octahedra. The corner-sharing octahedral tilt angles are 60°. Sm(1) is bonded to six equivalent O(1) atoms to form SmO6 octahedra that share corners with six equivalent Sr(1)O4 tetrahedra and edges with six equivalent Sm(1)O6 octahedra. O(1) is bonded to one Sr(1) and three equivalent Sm(1) atoms to form a mixture of distorted edge and corner-sharing OSrSm3 tetrahedra. is represented by the CIF file [CIF]
