Materials Data on Dy5AgS8 by Materials Project

Abstract

Dy5AgS8 crystallizes in the tetragonal I-4 space group. The structure is three-dimensional. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Dy–S bond distances ranging from 2.73–3.10 Å. In the second Dy3+ site, Dy3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are four shorter (2.74 Å) and four longer (2.99 Å) Dy–S bond lengths. Ag1+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are four shorter (2.77 Å) and four longer (3.14 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 Dy3+ and one Ag1+ atom. In the second S2- site, S2- is bonded in a 6-coordinate geometry to five Dy3+ and one Ag1+ atom.
