The crystal structure described by RbEuO2 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 Eu(1)O6 octahedra, edges with six equivalent Rb(1)O6 octahedra, and edges with six equivalent Eu(1)O6 octahedra. The corner-sharing octahedral tilt angles are 16°. Eu(1) is bonded to six equivalent O(1) atoms to form EuO6 octahedra that share corners with six equivalent Rb(1)O6 octahedra, edges with six equivalent Rb(1)O6 octahedra, and edges with six equivalent Eu(1)O6 octahedra. The corner-sharing octahedral tilt angles are 16°. O(1) is bonded to three equivalent Rb(1) and three equivalent Eu(1) atoms to form a mixture of distorted edge and corner-sharing ORb3Eu3 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF file [CIF]
