Materials Data on LiDySe2 by Materials Project
Abstract
LiDySe2 is Caswellsilverite-like structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Li1+ is bonded to six Se2- atoms to form LiSe6 octahedra that share corners with two equivalent DySe6 octahedra, corners with four equivalent LiSe6 octahedra, edges with four equivalent LiSe6 octahedra, and edges with eight equivalent DySe6 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. There are four shorter (2.85 Å) and two longer (2.93 Å) Li–Se bond lengths. Dy3+ is bonded to six Se2- atoms to form DySe6 octahedra that share corners with two equivalent LiSe6 octahedra, corners with four equivalent DySe6 octahedra, edges with four equivalent DySe6 octahedra, and edges with eight equivalent LiSe6 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. There are four shorter (2.85 Å) and two longer (2.86 Å) Dy–Se bond lengths. There are five inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to three equivalent Li1+ and three equivalent Dy3+ atoms to form a mixture of corner and edge-sharing SeLi3Dy3 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. There are two shorter (2.85 Å) and one longer (2.86 Å) Se–Dy bond lengths. In the second Se2- site, Se2- is bonded tomore »
