Title: Materials Data on CeSmO2 by Materials Project

Abstract

SmCeO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Sm is bonded to six equivalent O atoms to form SmO6 octahedra that share corners with six equivalent CeO6 octahedra, edges with six equivalent SmO6 octahedra, and edges with six equivalent CeO6 octahedra. The corner-sharing octahedral tilt angles are 1°. All Sm–O bond lengths are 2.46 Å. Ce is bonded to six equivalent O atoms to form CeO6 octahedra that share corners with six equivalent SmO6 octahedra, edges with six equivalent SmO6 octahedra, and edges with six equivalent CeO6 octahedra. The corner-sharing octahedral tilt angles are 1°. All Ce–O bond lengths are 2.51 Å. O is bonded to three equivalent Sm and three equivalent Ce atoms to form a mixture of edge and corner-sharing OCe3Sm3 octahedra. The corner-sharing octahedral tilt angles are 0°.
