The material described by Cs2O is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent O(1) atoms. In the second Cs site, Cs(2) is bonded in a distorted water-like geometry to two equivalent O(1) atoms. O(1) is bonded in a 5-coordinate geometry to two equivalent Cs(2) and three equivalent Cs(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
