Materials Data on LiNdSe2 by Materials Project
LiNdSe2 is Caswellsilverite-like structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Li1+ is bonded to six Se2- atoms to form LiSe6 octahedra that share corners with six equivalent LiSe6 octahedra, edges with four equivalent LiSe6 octahedra, and edges with eight equivalent NdSe6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.88 Å) and four longer (2.98 Å) Li–Se bond lengths. Nd3+ is bonded to six Se2- atoms to form NdSe6 octahedra that share corners with six equivalent NdSe6 octahedra, edges with four equivalent NdSe6 octahedra, and edges with eight equivalent LiSe6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.88 Å) and four longer (2.98 Å) Nd–Se bond lengths. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to two equivalent Li1+ and four equivalent Nd3+ atoms to form a mixture of edge and corner-sharing SeLi2Nd4 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second Se2- site, Se2- is bonded to four equivalent Li1+ and two equivalent Nd3+ atoms to form SeLi4Nd2 octahedra that share corners with six equivalent SeLi4Nd2 octahedra and edges with twelve SeLi2Nd4 octahedra. The corner-sharing octahedral tilt angles are 0°.
