Materials Data on Rb2CuF6 by Materials Project
Rb2CuF6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Rb is bonded to twelve equivalent F atoms to form RbF12 cuboctahedra that share corners with twelve equivalent RbF12 cuboctahedra, faces with six equivalent RbF12 cuboctahedra, and faces with four equivalent CuF6 octahedra. All Rb–F bond lengths are 3.07 Å. Cu is bonded to six equivalent F atoms to form CuF6 octahedra that share faces with eight equivalent RbF12 cuboctahedra. All Cu–F bond lengths are 1.86 Å. F is bonded in a single-bond geometry to four equivalent Rb and one Cu atom.
