The compound described by Ag2ZnSnS4 is Stannite structured and crystallizes in the tetragonal I-42m space group. Ag(1) 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 Sn(1)S4 tetrahedra. Zn(1) is bonded to four equivalent S(1) atoms to form ZnS4 tetrahedra that share corners with four equivalent Sn(1)S4 tetrahedra and corners with eight equivalent Ag(1)S4 tetrahedra. Sn(1) is bonded to four equivalent S(1) atoms to form SnS4 tetrahedra that share corners with four equivalent Zn(1)S4 tetrahedra and corners with eight equivalent Ag(1)S4 tetrahedra. S(1) is bonded to two equivalent Ag(1), one Zn(1), and one Sn(1) atom to form corner-sharing SZnAg2Sn tetrahedra. is represented by the CIF file [CIF]
