RbYbF3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Rb(1) is bonded to twelve equivalent F(1) atoms to form RbF12 cuboctahedra that share corners with twelve equivalent Rb(1)F12 cuboctahedra, faces with six equivalent Rb(1)F12 cuboctahedra, and faces with eight equivalent Yb(1)F6 octahedra. Yb(1) is bonded to six equivalent F(1) atoms to form YbF6 octahedra that share corners with six equivalent Yb(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a distorted linear geometry to four equivalent Rb(1) and two equivalent Yb(1) atoms.
