The structure described by Cs2Se is Cuprite structured and crystallizes in the cubic Pn-3m space group. Cs(1) is bonded in a linear geometry to two equivalent Se(1) atoms. Se(1) is bonded to four equivalent Cs(1) atoms to form corner-sharing SeCs4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
