Materials Data on Gd5AgS8 by Materials Project
Gd5AgS8 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. there are two inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Gd–S bond distances ranging from 2.76–3.08 Å. In the second Gd3+ site, Gd3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are four shorter (2.77 Å) and four longer (2.99 Å) Gd–S bond lengths. Ag1+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are four shorter (2.78 Å) and four longer (3.12 Å) Ag–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to five Gd3+ and one Ag1+ atom. In the second S2- site, S2- is bonded in a 6-coordinate geometry to five Gd3+ and one Ag1+ atom.
