The crystal structure described by PrYO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Pr(1) is bonded to six equivalent O(1) atoms to form PrO6 octahedra that share corners with six equivalent Y(1)O6 octahedra, edges with six equivalent Pr(1)O6 octahedra, and edges with six equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles are 11°. Y(1) is bonded to six equivalent O(1) atoms to form YO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra, edges with six equivalent Pr(1)O6 octahedra, and edges with six equivalent Y(1)O6 octahedra. The corner-sharing octahedral tilt angles are 11°. O(1) is bonded to three equivalent Pr(1) and three equivalent Y(1) atoms to form a mixture of corner and edge-sharing OPr3Y3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
