Materials Data on CdCu2GeSe4 by Materials Project
Cu2CdGeSe4 is Stannite structured and crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. Cu1+ is bonded to four equivalent Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent CuSe4 tetrahedra, corners with four equivalent CdSe4 tetrahedra, and corners with four equivalent GeSe4 tetrahedra. All Cu–Se bond lengths are 2.43 Å. Cd2+ is bonded to four equivalent Se2- atoms to form CdSe4 tetrahedra that share corners with four equivalent GeSe4 tetrahedra and corners with eight equivalent CuSe4 tetrahedra. All Cd–Se bond lengths are 2.69 Å. Ge4+ is bonded to four equivalent Se2- atoms to form GeSe4 tetrahedra that share corners with four equivalent CdSe4 tetrahedra and corners with eight equivalent CuSe4 tetrahedra. All Ge–Se bond lengths are 2.45 Å. Se2- is bonded to two equivalent Cu1+, one Cd2+, and one Ge4+ atom to form corner-sharing SeCdCu2Ge tetrahedra.
