Cs(TeO3)2 crystallizes in the trigonal R-3m space group. Cs(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form distorted CsO6 octahedra that share corners with three equivalent Te(2)O6 octahedra and corners with nine equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 63-74°. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form TeO6 octahedra that share corners with two equivalent Te(2)O6 octahedra, corners with four equivalent Te(1)O6 octahedra, and corners with six equivalent Cs(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 41-70°. In the second Te site, Te(2) is bonded to six equivalent O(2) atoms to form TeO6 octahedra that share corners with six equivalent Cs(1)O6 octahedra and corners with six equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-74°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Cs(1) and two equivalent Te(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Cs(1), one Te(1), and one Te(2) atom.
