The Materials Project

Rb2O is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent O2- atoms. There are one shorter (2.75 Å) and two longer (3.05 Å) Rb–O bond lengths. In the second Rb1+ site, Rb1+ is bonded to four equivalent O2- atoms to form a mixture of edge and corner-sharing RbO4 tetrahedra. There are a spread of Rb–O bond distances ranging from 2.87–2.99 Å. O2- is bonded in a 7-coordinate geometry to seven Rb1+ atoms.
