The structure described by Cs2CuO2 crystallizes in the tetragonal I4/mmm space group. Cs(1) is bonded in a linear geometry to two equivalent O(1) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded in a square co-planar geometry to two equivalent Cs(1) and two equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
