Title: Materials Data on LiFeAs by Materials Project

Abstract

LiFeAs crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Li1+ is bonded to three equivalent Fe2+ and five equivalent As3- atoms to form LiFe3As5 hexagonal bipyramids that share corners with two equivalent LiFe3As5 hexagonal bipyramids, corners with three equivalent AsLi5Fe3 hexagonal bipyramids, edges with three equivalent AsLi5Fe3 hexagonal bipyramids, and edges with twelve equivalent LiFe3As5 hexagonal bipyramids. All Li–Fe bond lengths are 2.52 Å. There are three shorter (2.52 Å) and two longer (2.57 Å) Li–As bond lengths. Fe2+ is bonded in a distorted hexagonal planar geometry to three equivalent Li1+ and three equivalent As3- atoms. All Fe–As bond lengths are 2.52 Å. As3- is bonded to five equivalent Li1+ and three equivalent Fe2+ atoms to form AsLi5Fe3 hexagonal bipyramids that share corners with two equivalent AsLi5Fe3 hexagonal bipyramids, corners with three equivalent LiFe3As5 hexagonal bipyramids, edges with three equivalent LiFe3As5 hexagonal bipyramids, and edges with twelve equivalent AsLi5Fe3 hexagonal bipyramids.
