The crystal structure described by RbF3 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded to four equivalent F(2) and eight equivalent F(1) atoms to form a mixture of distorted corner and face-sharing RbF12 cuboctahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted see-saw-like geometry to four equivalent Rb(1) atoms. In the second F site, F(2) is bonded in a 4-coordinate geometry to four equivalent Rb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
