The material structure described by Cs2O crystallizes in the orthorhombic Pnnm space group. Cs(1) is bonded in a distorted trigonal planar geometry to three equivalent O(1) atoms. O(1) is bonded to six equivalent Cs(1) atoms to form a mixture of distorted corner and edge-sharing OCs6 octahedra. The corner-sharing octahedral tilt angles are 59°. is represented by the CIF card [CIF]
