The structure described by Cs2O3 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded to twelve equivalent O(1) atoms to form CsO12 cuboctahedra that share corners with twelve equivalent Cs(1)O12 cuboctahedra, faces with six equivalent Cs(1)O12 cuboctahedra, and faces with eight equivalent Cs(2)O6 octahedra. In the second Cs site, Cs(2) is bonded to six equivalent O(1) atoms to form CsO6 octahedra that share corners with six equivalent Cs(2)O6 octahedra and faces with eight equivalent Cs(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent Cs(2) and four equivalent Cs(1) atoms. is represented by the CIF card [CIF]
