Abstract

Ag2ZnSiS4 is Stannite-like structured and crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are two inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded to four 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 SiS4 tetrahedra. There are a spread of Ag–S bond distances ranging from 2.53–2.60 Å. In the second Ag1+ site, Ag1+ is bonded to four 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 SiS4 tetrahedra. There are a spread of Ag–S bond distances ranging from 2.57–2.64 Å. Zn2+ is bonded to four S2- atoms to form ZnS4 tetrahedra that share corners with four equivalent SiS4 tetrahedra and corners with eight AgS4 tetrahedra. There are a spread of Zn–S bond distances ranging from 2.35–2.39 Å. Si4+ is bonded to four S2- atoms to form SiS4 tetrahedra that share corners with four equivalent ZnS4 tetrahedra and corners with eight AgS4 tetrahedra. There are three shorter (2.15 Å) and one longer (2.16 Å) Si–S bond lengths. There are four inequivalentmore »« less
