The compound described by RbF3 crystallizes in the tetragonal I4/mmm space group. Rb(1) is bonded to four equivalent F(2) and eight equivalent F(1) atoms to form a mixture of corner, face, and edge-sharing RbF12 cuboctahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to four equivalent Rb(1) atoms. In the second F site, F(2) is bonded in a square co-planar geometry to four equivalent Rb(1) atoms. is represented by the CIF file [CIF]
