The structure described by RbF3 crystallizes in the monoclinic P2_1 space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 11-coordinate geometry to one F(1), one F(5), two equivalent F(3), two equivalent F(4), two equivalent F(6), and three equivalent F(2) atoms. In the second Rb site, Rb(2) is bonded in a 11-coordinate geometry to one F(2), one F(6), two equivalent F(3), two equivalent F(4), two equivalent F(5), and three equivalent F(1) atoms. There are six inequivalent F sites. In the first F site, F(1) is bonded in a 5-coordinate geometry to one Rb(1), three equivalent Rb(2), and one F(5) atom. In the second F site, F(2) is bonded in a 5-coordinate geometry to one Rb(2), three equivalent Rb(1), and one F(6) atom. In the third F site, F(3) is bonded in a 4-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), and one F(6) atom. In the fourth F site, F(4) is bonded in a 4-coordinate geometry to two equivalent Rb(1), two equivalent Rb(2), and one F(5) atom. In the fifth F site, F(5) is bonded in a 5-coordinate geometry to one Rb(1), two equivalent Rb(2), one F(1), and one F(4) atom. In the sixth F site, F(6) is bonded in a 5-coordinate geometry to one Rb(2), two equivalent Rb(1), one F(2), and one F(3) atom. is represented by the CIF card [CIF]
