The material described by Zn2GeS4 crystallizes in the tetragonal I-42m space group. Zn(1) is bonded to four equivalent S(1) atoms to form ZnS4 tetrahedra that share corners with four equivalent Zn(1)S4 tetrahedra and corners with four equivalent Ge(1)S4 tetrahedra. Ge(1) is bonded to four equivalent S(1) atoms to form GeS4 tetrahedra that share corners with eight equivalent Zn(1)S4 tetrahedra. S(1) is bonded in a trigonal non-coplanar geometry to two equivalent Zn(1) and one Ge(1) atom. is represented by the CIF file [CIF]
