The compound described by KPrO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. K(1) is bonded to six equivalent O(1) atoms to form KO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra, edges with six equivalent K(1)O6 octahedra, and edges with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 12°. Pr(1) is bonded to six equivalent O(1) atoms to form PrO6 octahedra that share corners with six equivalent K(1)O6 octahedra, edges with six equivalent K(1)O6 octahedra, and edges with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 12°. O(1) is bonded to three equivalent K(1) and three equivalent Pr(1) atoms to form a mixture of edge and corner-sharing OK3Pr3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
