CuTeO3 crystallizes in the orthorhombic Pnma space group. Cu(1) is bonded in a 5-coordinate geometry to one O(1), one O(2), one O(3), and two equivalent O(4) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a see-saw-like geometry to one O(1), one O(2), and two equivalent O(3) atoms. In the second Te site, Te(2) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Cu(1) and one Te(2) atom. In the second O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Cu(1), one Te(1), and one Te(2) atom. In the third O site, O(2) is bonded in a 4-coordinate geometry to two equivalent Cu(1), one Te(1), and one Te(2) atom. In the fourth O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Cu(1) and one Te(1) atom.
