Materials Data on PrSbPt by Materials Project
PrPtSb crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Pr3+ is bonded to six equivalent Pt2- and six equivalent Sb1- atoms to form a mixture of distorted edge and face-sharing PrSb6Pt6 cuboctahedra. There are three shorter (3.17 Å) and three longer (3.55 Å) Pr–Pt bond lengths. There are three shorter (3.29 Å) and three longer (3.41 Å) Pr–Sb bond lengths. Pt2- is bonded in a 9-coordinate geometry to six equivalent Pr3+ and three equivalent Sb1- atoms. All Pt–Sb bond lengths are 2.68 Å. Sb1- is bonded in a 9-coordinate geometry to six equivalent Pr3+ and three equivalent Pt2- atoms.
