CrCu3ZnSe4 crystallizes in the cubic P-43m space group. Cr(1) is bonded to four equivalent Se(1) atoms to form distorted CrSe4 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 distorted 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 Cr(1)Se4 tetrahedra. Zn(1) is bonded to four equivalent Se(1) atoms to form ZnSe4 tetrahedra that share corners with four equivalent Cr(1)Se4 tetrahedra and corners with twelve equivalent Cu(1)Se4 tetrahedra. Se(1) is bonded in a distorted pentagonal planar geometry to one Cr(1), three equivalent Cu(1), and one Zn(1) atom.
