The material structure described by Rb5Sb4 crystallizes in the monoclinic Cm space group. There are five inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 6-coordinate geometry to one Sb(2), two equivalent Sb(3), and three equivalent Sb(1) atoms. In the second Rb site, Rb(2) is bonded in a 6-coordinate geometry to one Sb(1), two equivalent Sb(4), and three equivalent Sb(2) atoms. In the third Rb site, Rb(3) is bonded in a 7-coordinate geometry to two equivalent Sb(1), two equivalent Sb(4), and three equivalent Sb(3) atoms. In the fourth Rb site, Rb(4) is bonded in a 7-coordinate geometry to two equivalent Sb(2), two equivalent Sb(3), and three equivalent Sb(4) atoms. In the fifth Rb site, Rb(5) is bonded in a distorted square co-planar geometry to two equivalent Sb(1) and two equivalent Sb(2) atoms. There are four inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 9-coordinate geometry to one Rb(2), two equivalent Rb(3), two equivalent Rb(5), three equivalent Rb(1), and one Sb(3) atom. In the second Sb site, Sb(2) is bonded in a 9-coordinate geometry to one Rb(1), two equivalent Rb(4), two equivalent Rb(5), three equivalent Rb(2), and one Sb(4) atom. In the third Sb site, Sb(3) is bonded in a 9-coordinate geometry to two equivalent Rb(1), two equivalent Rb(4), three equivalent Rb(3), one Sb(1), and one Sb(4) atom. In the fourth Sb site, Sb(4) is bonded in a 9-coordinate geometry to two equivalent Rb(2), two equivalent Rb(3), three equivalent Rb(4), one Sb(2), and one Sb(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
