The crystal structure described by CsTe4 crystallizes in the monoclinic P2_1/c space group. Cs(1) is bonded in a 8-coordinate geometry to one Te(3), two equivalent Te(4), three equivalent Te(1), and three equivalent Te(2) atoms. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted pentagonal planar geometry to three equivalent Cs(1), one Te(1), and one Te(3) atom. In the second Te site, Te(2) is bonded in a 6-coordinate geometry to three equivalent Cs(1), one Te(4), and two equivalent Te(3) atoms. In the third Te site, Te(3) is bonded in a 5-coordinate geometry to one Cs(1), one Te(1), one Te(4), and two equivalent Te(2) atoms. In the fourth Te site, Te(4) is bonded in a 4-coordinate geometry to two equivalent Cs(1), one Te(2), and one Te(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
