Rb3SbF6 crystallizes in the triclinic P-1 space group. There are three inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a distorted hexagonal planar geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. In the second Rb site, Rb(2) is bonded in a distorted hexagonal planar geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. In the third Rb site, Rb(3) is bonded in a distorted hexagonal planar geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. Sb(1) is bonded in an octahedral geometry to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 4-coordinate geometry to one Rb(1), one Rb(2), one Rb(3), and one Sb(1) atom. In the second F site, F(2) is bonded in a rectangular see-saw-like geometry to one Rb(1), one Rb(2), one Rb(3), and one Sb(1) atom. In the third F site, F(3) is bonded in a distorted rectangular see-saw-like geometry to one Rb(1), one Rb(2), one Rb(3), and one Sb(1) atom.
