YCu3ZnSe4 crystallizes in the cubic P-43m space group. Y(1) is bonded to six equivalent Cu(1) and four equivalent Se(1) atoms to form distorted YCu6Se4 tetrahedra that share corners with four equivalent Zn(1)Se4 tetrahedra and corners with six equivalent Y(1)Cu6Se4 tetrahedra. Cu(1) is bonded in a 6-coordinate geometry to two equivalent Y(1) and four equivalent Se(1) atoms. Zn(1) is bonded to four equivalent Se(1) atoms to form ZnSe4 tetrahedra that share corners with four equivalent Y(1)Cu6Se4 tetrahedra. Se(1) is bonded in a distorted pentagonal planar geometry to one Y(1), three equivalent Cu(1), and one Zn(1) atom.
