Materials Data on RbNdSe2 by Materials Project
RbNdSe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Rb1+ is bonded to six equivalent Se2- atoms to form distorted RbSe6 octahedra that share corners with six equivalent NdSe6 octahedra, edges with six equivalent RbSe6 octahedra, and edges with six equivalent NdSe6 octahedra. The corner-sharing octahedral tilt angles are 11°. All Rb–Se bond lengths are 3.49 Å. Nd3+ is bonded to six equivalent Se2- atoms to form NdSe6 octahedra that share corners with six equivalent RbSe6 octahedra, edges with six equivalent RbSe6 octahedra, and edges with six equivalent NdSe6 octahedra. The corner-sharing octahedral tilt angles are 11°. All Nd–Se bond lengths are 3.00 Å. Se2- is bonded to three equivalent Rb1+ and three equivalent Nd3+ atoms to form a mixture of edge and corner-sharing SeRb3Nd3 octahedra. The corner-sharing octahedral tilt angles are 0°.
