The material structure described by Cu2Zn(TeO4)2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 5-coordinate geometry to one O(1), one O(3), one O(5), one O(6), and one O(7) atom. In the second Cu site, Cu(2) is bonded in a rectangular see-saw-like geometry to one O(2), one O(4), one O(6), and one O(8) atom. Zn(1) is bonded to one O(1), one O(4), one O(7), one O(8), and two equivalent O(3) atoms to form ZnO6 octahedra that share corners with three equivalent Te(1)O4 tetrahedra, corners with three equivalent Te(2)O4 trigonal pyramids, and  an edgeedge with one Zn(1)O6 octahedra. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to one O(1), one O(2), one O(4), and one O(7) atom to form TeO4 tetrahedra that share corners with three equivalent Zn(1)O6 octahedra.
