The crystal structure described by Cu2ZnGeS4 is Stannite structured and crystallizes in the tetragonal I-42m space group. Cu(1) is bonded to four equivalent S(1) atoms to form CuS4 tetrahedra that share corners with four equivalent Cu(1)S4 tetrahedra, corners with four equivalent Zn(1)S4 tetrahedra, and corners with four equivalent Ge(1)S4 tetrahedra. Zn(1) is bonded to four equivalent S(1) atoms to form ZnS4 tetrahedra that share corners with four equivalent Ge(1)S4 tetrahedra and corners with eight equivalent Cu(1)S4 tetrahedra. Ge(1) is bonded to four equivalent S(1) atoms to form GeS4 tetrahedra that share corners with four equivalent Zn(1)S4 tetrahedra and corners with eight equivalent Cu(1)S4 tetrahedra. S(1) is bonded to two equivalent Cu(1), one Zn(1), and one Ge(1) atom to form corner-sharing SZnCu2Ge tetrahedra. is represented by the CIF file [CIF]
