The structure described by Rb crystallizes in the triclinic P1 space group. There are eight inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 7-coordinate geometry to one Rb(4), two equivalent Rb(2), two equivalent Rb(3), and two equivalent Rb(8) atoms. In the second Rb site, Rb(2) is bonded in a 7-coordinate geometry to one Rb(7), two equivalent Rb(1), two equivalent Rb(5), and two equivalent Rb(6) atoms. In the third Rb site, Rb(3) is bonded in a 9-coordinate geometry to one Rb(8), two equivalent Rb(1), two equivalent Rb(5), two equivalent Rb(6), and two equivalent Rb(7) atoms. In the fourth Rb site, Rb(4) is bonded in a distorted hexagonal planar geometry to one Rb(1), one Rb(5), two equivalent Rb(6), and two equivalent Rb(7) atoms. In the fifth Rb site, Rb(5) is bonded in a 7-coordinate geometry to one Rb(4), one Rb(6), two equivalent Rb(2), two equivalent Rb(3), and two equivalent Rb(8) atoms. In the sixth Rb site, Rb(6) is bonded in a 9-coordinate geometry to one Rb(5), two equivalent Rb(2), two equivalent Rb(3), two equivalent Rb(4), and two equivalent Rb(8) atoms. In the seventh Rb site, Rb(7) is bonded in a 7-coordinate geometry to one Rb(2), two equivalent Rb(3), two equivalent Rb(4), and two equivalent Rb(8) atoms. In the eighth Rb site, Rb(8) is bonded in a 9-coordinate geometry to one Rb(3), two equivalent Rb(1), two equivalent Rb(5), two equivalent Rb(6), and two equivalent Rb(7) atoms. is represented by the CIF card [CIF]
