The structure described by CoCu2TeO6 is Hausmannite-derived structured and crystallizes in the orthorhombic I2_12_12_1 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form distorted CoO6 octahedra that share corners with two equivalent Co(2)O6 octahedra, corners with two equivalent Te(1)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-62°. In the second Co site, Co(2) is bonded to two equivalent O(1), two equivalent O(5), and two equivalent O(6) atoms to form distorted CoO6 octahedra that share corners with two equivalent Co(1)O6 octahedra, corners with two equivalent Te(1)O6 octahedra, and edges with two equivalent Te(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-62°. There are four inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(4), and two equivalent O(6) atoms. In the second Cu site, Cu(2) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(6) atoms. In the third Cu site, Cu(3) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the fourth Cu site, Cu(4) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(3), and two equivalent O(5) atoms. Te(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(6) atom to form TeO6 octahedra that share  a cornercorner with one Co(1)O6 octahedra,  a cornercorner with one Co(2)O6 octahedra,  an edgeedge with one Co(1)O6 octahedra, and  an edgeedge with one Co(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-48°. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Co(2), one Cu(2), one Cu(4), and one Te(1) atom. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Cu(1), one Cu(2), one Cu(3), and one Te(1) atom. In the third O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Co(1), one Cu(3), one Cu(4), and one Te(1) atom. In the fourth O site, O(4) is bonded in a distorted rectangular see-saw-like geometry to one Co(1), one Cu(1), one Cu(3), and one Te(1) atom.
