Materials Data on PrSb2Au by Materials Project
PrAuSb2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Pr3+ is bonded in a 8-coordinate geometry to eight Sb3- atoms. There are four shorter (3.26 Å) and four longer (3.39 Å) Pr–Sb bond lengths. Au3+ is bonded to four equivalent Sb3- atoms to form a mixture of edge and corner-sharing AuSb4 tetrahedra. All Au–Sb bond lengths are 2.89 Å. There are two inequivalent Sb3- sites. In the first Sb3- site, Sb3- is bonded in a 8-coordinate geometry to four equivalent Pr3+ and four equivalent Sb3- atoms. All Sb–Sb bond lengths are 3.16 Å. In the second Sb3- site, Sb3- is bonded in a 8-coordinate geometry to four equivalent Pr3+ and four equivalent Au3+ atoms.
