The crystal structure described by Rb is Tungsten structured and crystallizes in the triclinic P1 space group. There are eight inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a body-centered cubic geometry to two equivalent Rb(2), two equivalent Rb(3), two equivalent Rb(4), and two equivalent Rb(8) atoms. In the second Rb site, Rb(2) is bonded in a body-centered cubic geometry to two equivalent Rb(1), two equivalent Rb(5), two equivalent Rb(6), and two equivalent Rb(7) atoms. In the third Rb site, Rb(3) is bonded in a body-centered cubic geometry to 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 body-centered cubic geometry to two equivalent Rb(1), two equivalent Rb(5), two equivalent Rb(6), and two equivalent Rb(7) atoms. In the fifth Rb site, Rb(5) is bonded in a body-centered cubic geometry to two equivalent Rb(2), two equivalent Rb(3), two equivalent Rb(4), and two equivalent Rb(8) atoms. In the sixth Rb site, Rb(6) is bonded in a body-centered cubic geometry to 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 body-centered cubic geometry to two equivalent 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 body-centered cubic geometry to two equivalent Rb(1), two equivalent Rb(5), two equivalent Rb(6), and two equivalent Rb(7) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
