Materials Data on NdSmO2 by Materials Project
SmNdO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Sm2+ is bonded to six equivalent O2- atoms to form SmO6 octahedra that share corners with six equivalent NdO6 octahedra, edges with six equivalent SmO6 octahedra, and edges with six equivalent NdO6 octahedra. The corner-sharing octahedral tilt angles are 4°. All Sm–O bond lengths are 2.44 Å. Nd2+ is bonded to six equivalent O2- atoms to form NdO6 octahedra that share corners with six equivalent SmO6 octahedra, edges with six equivalent SmO6 octahedra, and edges with six equivalent NdO6 octahedra. The corner-sharing octahedral tilt angles are 4°. All Nd–O bond lengths are 2.58 Å. O2- is bonded to three equivalent Sm2+ and three equivalent Nd2+ atoms to form a mixture of edge and corner-sharing ONd3Sm3 octahedra. The corner-sharing octahedral tilt angles are 0°.
