CuTe2O5 is Antimony trioxide-derived structured and crystallizes in the monoclinic P2_1/c space group. Cu(1) is bonded to one O(2), one O(3), one O(4), and two equivalent O(1) atoms to form edge-sharing CuO5 square pyramids. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted rectangular see-saw-like geometry to one O(1), one O(2), one O(3), and one O(5) atom. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to one O(2), one O(5), and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Cu(1) and one Te(1) atom. In the second O site, O(2) is bonded in a trigonal non-coplanar geometry to one Cu(1), one Te(1), and one Te(2) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Cu(1) and one Te(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Cu(1) and two equivalent Te(2) atoms. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Te(1) and one Te(2) atom.
