RbTbO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Rb(1) is bonded to twelve equivalent O(1) atoms to form RbO12 cuboctahedra that share corners with twelve equivalent Rb(1)O12 cuboctahedra, faces with six equivalent Rb(1)O12 cuboctahedra, and faces with eight equivalent Tb(1)O6 octahedra. Tb(1) is bonded to six equivalent O(1) atoms to form TbO6 octahedra that share corners with six equivalent Tb(1)O6 octahedra and faces with eight equivalent Rb(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to four equivalent Rb(1) and two equivalent Tb(1) atoms.
