The crystal structure described by SmNdO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Sm(1) is bonded to six equivalent O(1) atoms to form SmO6 octahedra that share corners with six equivalent Nd(1)O6 octahedra, edges with six equivalent Sm(1)O6 octahedra, and edges with six equivalent Nd(1)O6 octahedra. The corner-sharing octahedral tilt angles are 4°. Nd(1) is bonded to six equivalent O(1) atoms to form NdO6 octahedra that share corners with six equivalent Sm(1)O6 octahedra, edges with six equivalent Sm(1)O6 octahedra, and edges with six equivalent Nd(1)O6 octahedra. The corner-sharing octahedral tilt angles are 4°. O(1) is bonded to three equivalent Sm(1) and three equivalent Nd(1) atoms to form a mixture of corner and edge-sharing ONd3Sm3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
