The crystal structure described by CoCu3ZnSe4 crystallizes in the cubic P-43m space group. Co(1) is bonded to four equivalent Se(1) atoms to form CoSe4 tetrahedra that share corners with four equivalent Zn(1)Se4 tetrahedra and edges with six equivalent Cu(1)Se4 tetrahedra. Cu(1) is bonded to four equivalent Se(1) atoms to form CuSe4 tetrahedra that share corners with four equivalent Zn(1)Se4 tetrahedra, corners with eight equivalent Cu(1)Se4 tetrahedra, and edges with two equivalent Co(1)Se4 tetrahedra. Zn(1) is bonded to four equivalent Se(1) atoms to form ZnSe4 tetrahedra that share corners with four equivalent Co(1)Se4 tetrahedra and corners with twelve equivalent Cu(1)Se4 tetrahedra. Se(1) is bonded in a distorted pentagonal planar geometry to one Co(1), three equivalent Cu(1), and one Zn(1) atom. is represented by the CIF file [CIF]
