The material described by RbNi2F6 crystallizes in the cubic Fd-3m space group. Rb(1) is bonded to six equivalent F(1) atoms to form RbF6 octahedra that share corners with twelve equivalent Ni(1)F6 octahedra. The corner-sharing octahedral tilt angles are 68°. Ni(1) is bonded to six equivalent F(1) atoms to form NiF6 octahedra that share corners with six equivalent Rb(1)F6 octahedra and corners with six equivalent Ni(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 44-68°. F(1) is bonded in a 2-coordinate geometry to one Rb(1) and two equivalent Ni(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
