Materials Data on ZnCu3NiSe4 by Materials Project
NiCu3ZnSe4 crystallizes in the cubic P-43m space group. The structure is three-dimensional. Ni2+ is bonded to four equivalent Se2- atoms to form NiSe4 tetrahedra that share corners with four equivalent ZnSe4 tetrahedra and edges with six equivalent CuSe4 tetrahedra. All Ni–Se bond lengths are 2.40 Å. Cu+1.33+ is bonded to four equivalent Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent ZnSe4 tetrahedra, corners with eight equivalent CuSe4 tetrahedra, and edges with two equivalent NiSe4 tetrahedra. All Cu–Se bond lengths are 2.43 Å. Zn2+ is bonded to four equivalent Se2- atoms to form ZnSe4 tetrahedra that share corners with four equivalent NiSe4 tetrahedra and corners with twelve equivalent CuSe4 tetrahedra. All Zn–Se bond lengths are 2.47 Å. Se2- is bonded in a distorted pentagonal planar geometry to one Ni2+, three equivalent Cu+1.33+, and one Zn2+ atom.
