Materials Data on PrAgSb2 by Materials Project

PrAgSb2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Pr3+ is bonded in a 8-coordinate geometry to eight Sb2- atoms. There are four shorter (3.27 Å) and four longer (3.39 Å) Pr–Sb bond lengths. Ag1+ is bonded in a 4-coordinate geometry to four equivalent Ag1+ and four equivalent Sb2- atoms. All Ag–Ag bond lengths are 3.13 Å. All Ag–Sb bond lengths are 2.91 Å. There are two inequivalent Sb2- sites. In the first Sb2- site, Sb2- is bonded in a 8-coordinate geometry to four equivalent Pr3+ and four equivalent Sb2- atoms. All Sb–Sb bond lengths are 3.13 Å. In the second Sb2- site, Sb2- is bonded in a 8-coordinate geometry to four equivalent Pr3+ and four equivalent Ag1+ atoms.

Materials Data on Pr2AgSb3 by Materials Project

(PrSb)2AgSb crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one antimony molecule, one silver molecule, and two PrSb clusters. In each PrSb cluster, Pr3+ is bonded in a single-bond geometry to one Sb+2.33- atom. The Pr–Sb bond length is 2.72 Å. Sb+2.33- is bonded in a single-bond geometry to one Pr3+ atom.
