Materials Data on PrSbPd by Materials Project

PrPdSb is hexagonal omega structure-derived structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pr is bonded to six equivalent Pd and six equivalent Sb atoms to form a mixture of edge and face-sharing PrSb6Pd6 cuboctahedra. All Pr–Pd bond lengths are 3.36 Å. All Pr–Sb bond lengths are 3.36 Å. Pd is bonded in a 9-coordinate geometry to six equivalent Pr and three equivalent Sb atoms. All Pd–Sb bond lengths are 2.67 Å. Sb is bonded in a 9-coordinate geometry to six equivalent Pr and three equivalent Pd atoms.

Materials Data on PrSbPd by Materials Project

PrPdSb crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. Pr is bonded in a 12-coordinate geometry to six equivalent Pd and six equivalent Sb atoms. There are three shorter (3.11 Å) and three longer (3.60 Å) Pr–Pd bond lengths. There are three shorter (3.26 Å) and three longer (3.42 Å) Pr–Sb bond lengths. Pd is bonded in a 6-coordinate geometry to six equivalent Pr and four equivalent Sb atoms. There are three shorter (2.74 Å) and one longer (3.42 Å) Pd–Sb bond lengths. Sb is bonded in a 10-coordinate geometry to six equivalent Pr and four equivalent Pd atoms.
