RbPrO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Rb(1) is bonded to six equivalent O(1) atoms to form distorted RbO6 octahedra that share corners with six equivalent Pr(1)O6 octahedra, edges with six equivalent Rb(1)O6 octahedra, and edges with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 15°. Pr(1) is bonded to six equivalent O(1) atoms to form PrO6 octahedra that share corners with six equivalent Rb(1)O6 octahedra, edges with six equivalent Rb(1)O6 octahedra, and edges with six equivalent Pr(1)O6 octahedra. The corner-sharing octahedral tilt angles are 15°. O(1) is bonded to three equivalent Rb(1) and three equivalent Pr(1) atoms to form a mixture of distorted corner and edge-sharing ORb3Pr3 octahedra. The corner-sharing octahedra are not tilted.
