The compound described by Rb6O crystallizes in the hexagonal P6_3/m space group. There are four inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a single-bond geometry to one Rb(4) and one O(1) atom. In the second Rb site, Rb(2) is bonded in an L-shaped geometry to two equivalent O(1) atoms. In the third Rb site, Rb(3) is bonded in a hexagonal planar geometry to six equivalent Rb(4) atoms. In the fourth Rb site, Rb(4) is bonded in a distorted q6 geometry to three equivalent Rb(1), three equivalent Rb(3), and three equivalent Rb(4) atoms. O(1) is bonded to three equivalent Rb(1) and three equivalent Rb(2) atoms to form face-sharing ORb6 octahedra. is represented by the CIF file [CIF]
