The structure described by Co2Zn(CuO4)2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(1), one O(2), one O(4), and one O(7) atom to form CoO4 tetrahedra that share corners with three equivalent Zn(1)O6 octahedra and corners with two equivalent Cu(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 35-49°. In the second Co site, Co(2) is bonded to one O(3), one O(5), one O(6), and one O(8) atom to form CoO4 tetrahedra that share corners with three equivalent Zn(1)O6 octahedra and corners with three equivalent Cu(1)O5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 58-61°. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded to one O(1), one O(3), one O(5), one O(6), and one O(7) atom to form CuO5 trigonal bipyramids that share corners with two equivalent Co(1)O4 tetrahedra, corners with three equivalent Co(2)O4 tetrahedra, and edges with two equivalent Zn(1)O6 octahedra. 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 Co(1)O4 tetrahedra, corners with three equivalent Co(2)O4 tetrahedra,  an edgeedge with one Zn(1)O6 octahedra, and edges with two equivalent Cu(1)O5 trigonal bipyramids. There are eight inequivalent O sites. In the first O site, O(7) is bonded in a 3-coordinate geometry to one Co(1), one Cu(1), and one Zn(1) atom. In the second O site, O(8) is bonded in a trigonal planar geometry to one Co(2), one Cu(2), and one Zn(1) atom.
