CsSbTeO6 crystallizes in the orthorhombic Imma space group. Cs(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form CsO6 octahedra that share corners with six equivalent Sb(1)O6 octahedra and corners with six equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 67-68°. Sb(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form SbO6 octahedra that share corners with two equivalent Sb(1)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 44-68°. Te(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form TeO6 octahedra that share corners with two equivalent Te(1)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra, and corners with six equivalent Cs(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 44-68°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate 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) and two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Cs(1), one Sb(1), and one Te(1) atom.
