The crystal structure described by Ag2ZnGeS4 is Stannite-like structured and crystallizes in the tetragonal I-4 space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent S(1) atoms to form AgS4 tetrahedra that share corners with four equivalent Ag(2)S4 tetrahedra, corners with four equivalent Zn(1)S4 tetrahedra, and corners with four equivalent Ge(1)S4 tetrahedra. In the second Ag site, Ag(2) is bonded to four equivalent S(1) atoms to form AgS4 tetrahedra that share corners with four equivalent Ag(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 Ag(1)S4 tetrahedra, corners with four equivalent Ag(2)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 four equivalent Ag(1)S4 tetrahedra, corners with four equivalent Ag(2)S4 tetrahedra, and corners with four equivalent Zn(1)S4 tetrahedra. S(1) is bonded to one Ag(1), one Ag(2), one Zn(1), and one Ge(1) atom to form corner-sharing SZnAg2Ge tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
