The crystal structure described by Cs2Te 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 5-coordinate geometry to five equivalent Te(1) atoms. In the second Cs site, Cs(2) is bonded to four equivalent Te(1) atoms to form a mixture of distorted edge and corner-sharing CsTe4 tetrahedra. Te(1) is bonded in a 9-coordinate geometry to four equivalent Cs(2) and five equivalent Cs(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
