The Materials Project

Cu2GeSe4 crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. Cu2+ is bonded to four equivalent Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent CuSe4 tetrahedra and corners with four equivalent GeSe4 tetrahedra. All Cu–Se bond lengths are 2.38 Å. Ge4+ is bonded to four equivalent Se2- atoms to form GeSe4 tetrahedra that share corners with eight equivalent CuSe4 tetrahedra. All Ge–Se bond lengths are 2.41 Å. Se2- is bonded in a trigonal non-coplanar geometry to two equivalent Cu2+ and one Ge4+ atom.
