Materials Data on La2YbS4 by Materials Project
YbLa2S4 crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Yb2+ is bonded to eight equivalent S2- atoms to form distorted YbS8 hexagonal bipyramids that share corners with eight equivalent LaS8 hexagonal bipyramids, edges with four equivalent YbS8 hexagonal bipyramids, and faces with eight equivalent LaS8 hexagonal bipyramids. There are four shorter (2.88 Å) and four longer (3.12 Å) Yb–S bond lengths. La3+ is bonded to eight equivalent S2- atoms to form distorted LaS8 hexagonal bipyramids that share corners with four equivalent YbS8 hexagonal bipyramids, corners with four equivalent LaS8 hexagonal bipyramids, edges with four equivalent LaS8 hexagonal bipyramids, faces with four equivalent YbS8 hexagonal bipyramids, and faces with four equivalent LaS8 hexagonal bipyramids. There are a spread of La–S bond distances ranging from 2.89–3.17 Å. S2- is bonded in a 6-coordinate geometry to two equivalent Yb2+ and four equivalent La3+ atoms.
