Materials Data on PrYO2 by Materials Project
PrYO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Pr is bonded to six equivalent O atoms to form PrO6 octahedra that share corners with six equivalent YO6 octahedra, edges with six equivalent PrO6 octahedra, and edges with six equivalent YO6 octahedra. The corner-sharing octahedral tilt angles are 11°. All Pr–O bond lengths are 2.69 Å. Y is bonded to six equivalent O atoms to form YO6 octahedra that share corners with six equivalent PrO6 octahedra, edges with six equivalent PrO6 octahedra, and edges with six equivalent YO6 octahedra. The corner-sharing octahedral tilt angles are 11°. All Y–O bond lengths are 2.33 Å. O is bonded to three equivalent Pr and three equivalent Y atoms to form a mixture of corner and edge-sharing OPr3Y3 octahedra. The corner-sharing octahedral tilt angles are 0°.
