Abstract

KSmO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. K1+ is bonded to six equivalent O2- atoms to form distorted KO6 octahedra that share corners with six equivalent SmO6 octahedra, edges with six equivalent KO6 octahedra, and edges with six equivalent SmO6 octahedra. The corner-sharing octahedral tilt angles are 13°. All K–O bond lengths are 2.85 Å. Sm3+ is bonded to six equivalent O2- atoms to form SmO6 octahedra that share corners with six equivalent KO6 octahedra, edges with six equivalent KO6 octahedra, and edges with six equivalent SmO6 octahedra. The corner-sharing octahedral tilt angles are 13°. All Sm–O bond lengths are 2.39 Å. O2- is bonded to three equivalent K1+ and three equivalent Sm3+ atoms to form a mixture of distorted edge and corner-sharing OK3Sm3 octahedra. The corner-sharing octahedral tilt angles are 0°.
