The crystal structure described by KSmO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. K(1) is bonded to six equivalent O(1) atoms to form distorted KO6 octahedra that share corners with six equivalent Sm(1)O6 octahedra, edges with six equivalent K(1)O6 octahedra, and edges with six equivalent Sm(1)O6 octahedra. The corner-sharing octahedral tilt angles are 13°. Sm(1) is bonded to six equivalent O(1) atoms to form SmO6 octahedra that share corners with six equivalent K(1)O6 octahedra, edges with six equivalent K(1)O6 octahedra, and edges with six equivalent Sm(1)O6 octahedra. The corner-sharing octahedral tilt angles are 13°. O(1) is bonded to three equivalent K(1) and three equivalent Sm(1) atoms to form a mixture of edge and corner-sharing OK3Sm3 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
