Materials Data on RbSmTe2 by Materials Project
RbSmTe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Rb1+ is bonded to six equivalent Te2- atoms to form distorted RbTe6 octahedra that share corners with six equivalent SmTe6 octahedra, edges with six equivalent RbTe6 octahedra, and edges with six equivalent SmTe6 octahedra. The corner-sharing octahedral tilt angles are 11°. All Rb–Te bond lengths are 3.68 Å. Sm3+ is bonded to six equivalent Te2- atoms to form SmTe6 octahedra that share corners with six equivalent RbTe6 octahedra, edges with six equivalent RbTe6 octahedra, and edges with six equivalent SmTe6 octahedra. The corner-sharing octahedral tilt angles are 11°. All Sm–Te bond lengths are 3.17 Å. Te2- is bonded to three equivalent Rb1+ and three equivalent Sm3+ atoms to form a mixture of edge and corner-sharing TeRb3Sm3 octahedra. The corner-sharing octahedral tilt angles are 0°.
