The structure described by Cs2Te3 crystallizes in the orthorhombic Cmc2_1 space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 8-coordinate geometry to two equivalent Te(1) and six equivalent Te(2) atoms. In the second Cs site, Cs(2) is bonded in a 7-coordinate geometry to one Te(1) and six equivalent Te(2) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a 5-coordinate geometry to one Cs(2), two equivalent Cs(1), and two equivalent Te(2) atoms. In the second Te site, Te(2) is bonded to three equivalent Cs(1), three equivalent Cs(2), and one Te(1) atom to form a mixture of distorted corner, face, and edge-sharing TeCs6Te pentagonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
