Cs2TeO3 is Krennerite-derived structured and crystallizes in the trigonal P321 space group. There are three inequivalent Cs sites. In the first Cs site, Cs(1) is bonded to six equivalent O(1) atoms to form distorted face-sharing CsO6 octahedra. In the second Cs site, Cs(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. In the third Cs site, Cs(3) is bonded to six equivalent O(1) atoms to form face-sharing CsO6 octahedra. Te(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent O(1) atoms. O(1) is bonded in a 1-coordinate geometry to one Cs(1), one Cs(3), two equivalent Cs(2), and one Te(1) atom.
Cs2TeO3 is Krennerite-derived structured and crystallizes in the trigonal P321 space group. There are three inequivalent Cs sites. In the first Cs site, Cs(1) is bonded to six equivalent O(1) atoms to form distorted face-sharing CsO6 octahedra. All Cs(1)-O(1) bond lengths are 3.16 Å. In the second Cs site, Cs(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are three shorter (3.18 Å) and three longer (3.36 Å) Cs(2)-O(1) bond lengths. In the third Cs site, Cs(3) is bonded to six equivalent O(1) atoms to form face-sharing CsO6 octahedra. All Cs(3)-O(1) bond lengths are 2.97 Å. Te(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent O(1) atoms. All Te(1)-O(1) bond lengths are 1.86 Å. O(1) is bonded in a 1-coordinate geometry to one Cs(1), one Cs(3), two equivalent Cs(2), and one Te(1) atom.
