The structure described by Rb2HfF6 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 Hf(1)F6 octahedra, faces with eight equivalent Rb(1)F12 cuboctahedra, and faces with three equivalent Hf(1)F6 octahedra. The corner-sharing octahedral tilt angles are 17°. Hf(1) is bonded to six equivalent F(1) atoms to form HfF6 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 Hf(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
