RbSmO2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. Rb(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. Sm(1) is bonded to six equivalent O(1) atoms to form edge-sharing SmO6 octahedra. O(1) is bonded to three equivalent Rb(1) and three equivalent Sm(1) atoms to form a mixture of distorted corner and edge-sharing ORb3Sm3 octahedra. The corner-sharing octahedra are not tilted.
