Materials Data on Pr5Sn3Au by Materials Project
Pr5AuSn3 crystallizes in the hexagonal P6_3/mcm space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 7-coordinate geometry to two equivalent Au and five equivalent Sn atoms. Both Pr–Au bond lengths are 3.11 Å. There are a spread of Pr–Sn bond distances ranging from 3.27–3.59 Å. In the second Pr site, Pr is bonded in a 6-coordinate geometry to six equivalent Sn atoms. All Pr–Sn bond lengths are 3.46 Å. Au is bonded to six equivalent Pr atoms to form face-sharing AuPr6 octahedra. Sn is bonded in a 9-coordinate geometry to nine Pr atoms.
