The compound described by Rb2O is Fluorite structured and crystallizes in the orthorhombic Pnnm space group. Rb(1) is bonded to four equivalent O(1) atoms to form a mixture of corner and edge-sharing RbO4 tetrahedra. O(1) is bonded in a body-centered cubic geometry to eight equivalent Rb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
