Materials Data on ZnAg2SnS4 by Materials Project
Ag2ZnSnS4 is Stannite structured and crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. Ag1+ is bonded to four equivalent S2- atoms to form AgS4 tetrahedra that share corners with four equivalent AgS4 tetrahedra, corners with four equivalent ZnS4 tetrahedra, and corners with four equivalent SnS4 tetrahedra. All Ag–S bond lengths are 2.56 Å. Zn2+ is bonded to four equivalent S2- atoms to form ZnS4 tetrahedra that share corners with four equivalent SnS4 tetrahedra and corners with eight equivalent AgS4 tetrahedra. All Zn–S bond lengths are 2.39 Å. Sn4+ is bonded to four equivalent S2- atoms to form SnS4 tetrahedra that share corners with four equivalent ZnS4 tetrahedra and corners with eight equivalent AgS4 tetrahedra. All Sn–S bond lengths are 2.46 Å. S2- is bonded to two equivalent Ag1+, one Zn2+, and one Sn4+ atom to form corner-sharing SZnAg2Sn tetrahedra.
