Abstract

CaSnS3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are seven inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six S2- atoms to form CaS6 octahedra that share corners with two equivalent SnS4 tetrahedra and edges with two equivalent SnS4 trigonal pyramids. There are a spread of Ca–S bond distances ranging from 2.75–3.20 Å. In the second Ca2+ site, Ca2+ is bonded in a 6-coordinate geometry to six S2- atoms. There are a spread of Ca–S bond distances ranging from 2.86–3.00 Å. In the third Ca2+ site, Ca2+ is bonded in a 6-coordinate geometry to six S2- atoms.
