Materials Data on Yb(GdS2)2 by Materials Project
Yb(GdS2)2 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 GdS8 hexagonal bipyramids, edges with four equivalent YbS8 hexagonal bipyramids, and faces with eight equivalent GdS8 hexagonal bipyramids. There are four shorter (2.81 Å) and four longer (3.03 Å) Yb–S bond lengths. Gd3+ is bonded to eight equivalent S2- atoms to form distorted GdS8 hexagonal bipyramids that share corners with four equivalent YbS8 hexagonal bipyramids, corners with four equivalent GdS8 hexagonal bipyramids, edges with four equivalent GdS8 hexagonal bipyramids, faces with four equivalent YbS8 hexagonal bipyramids, and faces with four equivalent GdS8 hexagonal bipyramids. There are a spread of Gd–S bond distances ranging from 2.80–3.02 Å. S2- is bonded to two equivalent Yb2+ and four equivalent Gd3+ atoms to form a mixture of distorted face, edge, and corner-sharing SYb2Gd4 octahedra. The corner-sharing octahedra tilt angles range from 17–50°.
