Abstract

Cs2SiS3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded to seven S2- atoms to form distorted CsS7 pentagonal bipyramids that share corners with four CsS7 pentagonal bipyramids, corners with three equivalent SiS4 tetrahedra, edges with eight CsS7 pentagonal bipyramids, edges with three equivalent SiS4 tetrahedra, and faces with two equivalent CsS7 pentagonal bipyramids. There are a spread of Cs–S bond distances ranging from 3.50–3.73 Å. In the second Cs1+ site, Cs1+ is bonded to seven S2- atoms to form distorted CsS7 pentagonal bipyramids that share corners with four CsS7 pentagonal bipyramids, corners with five equivalent SiS4 tetrahedra, edges with eight CsS7 pentagonal bipyramids, edges with two equivalent SiS4 tetrahedra, and faces with two equivalent CsS7 pentagonal bipyramids. There are a spread of Cs–S bond distances ranging from 3.53–4.02 Å. Si4+ is bonded to four S2- atoms to form SiS4 tetrahedra that share corners with eight CsS7 pentagonal bipyramids, edges with five CsS7 pentagonal bipyramids, and an edgeedge with one SiS4 tetrahedra. There are a spread of Si–S bond distances ranging from 2.09–2.22 Å. There are three inequivalent S2- sites. In the first S2-more »« less
