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.
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 shorter (2.89 Å) and two longer (3.28 Å) Rb(1)-F(2) bond lengths. There are a spread of Rb(1)-F(1) bond distances ranging from 2.90-3.10 Å. 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.
