Rb2GeF6 crystallizes in the trigonal P-3m1 space group. Rb(1) is bonded to twelve equivalent F(1) atoms to form distorted RbF12 cuboctahedra that share corners with six equivalent Rb(1)F12 cuboctahedra, corners with three equivalent Ge(1)F6 octahedra, faces with eight equivalent Rb(1)F12 cuboctahedra, and faces with three equivalent Ge(1)F6 octahedra. The corner-sharing octahedral tilt angles are 17°. Ge(1) is bonded to six equivalent F(1) atoms to form GeF6 octahedra that share corners with six equivalent Rb(1)F12 cuboctahedra and faces with six equivalent Rb(1)F12 cuboctahedra. F(1) is bonded in a distorted single-bond geometry to four equivalent Rb(1) and one Ge(1) atom.
