# Materials Data on PrY by Materials Project

## Abstract

YPr is beta-derived structured and crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are four inequivalent Pr sites. In the first Pr site, Pr is bonded to nine Pr and three equivalent Y atoms to form PrPr9Y3 cuboctahedra that share corners with six equivalent PrPr9Y3 cuboctahedra, corners with twelve YPr3Y9 cuboctahedra, edges with six equivalent YPr3Y9 cuboctahedra, edges with twelve PrPr9Y3 cuboctahedra, faces with eight YPr3Y9 cuboctahedra, and faces with twelve PrPr9Y3 cuboctahedra. There are six shorter (3.67 Å) and three longer (3.72 Å) Pr–Pr bond lengths. All Pr–Y bond lengths are 3.60 Å. In the second Pr site, Pr is bonded to six equivalent Pr and six Y atoms to form PrPr6Y6 cuboctahedra that share corners with six equivalent YPr3Y9 cuboctahedra, corners with twelve PrPr6Y6 cuboctahedra, edges with six equivalent PrPr6Y6 cuboctahedra, edges with twelve YPr3Y9 cuboctahedra, faces with seven PrPr6Y6 cuboctahedra, and faces with thirteen YPr3Y9 cuboctahedra. All Pr–Pr bond lengths are 3.67 Å. There are three shorter (3.62 Å) and three longer (3.64 Å) Pr–Y bond lengths. In the third Pr site, Pr is bonded to nine Pr and three equivalent Y atoms to form PrPr9Y3 cuboctahedra that share corners with three equivalentmore »
