CuTeO4 is Hydrophilite-derived structured and crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CuO6 octahedra that share corners with four equivalent Cu(2)O6 octahedra, corners with four equivalent Te(1)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-59°. In the second Cu site, Cu(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form CuO6 octahedra that share corners with four equivalent Cu(1)O6 octahedra, corners with four equivalent Te(1)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-59°. Te(1) is bonded to one O(1), one O(2), two equivalent O(3), and two equivalent O(4) atoms to form TeO6 octahedra that share corners with two equivalent Cu(1)O6 octahedra, corners with two equivalent Cu(2)O6 octahedra, corners with four equivalent Te(1)O6 octahedra,  an edgeedge with one Cu(1)O6 octahedra, and  an edgeedge with one Cu(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-53°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Cu(1), one Cu(2), and one Te(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Cu(1), one Cu(2), and one Te(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Cu(1) and two equivalent Te(1) atoms. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Cu(2) and two equivalent Te(1) atoms.
