Abstract

CaSnS3 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six S2- atoms to form distorted CaS6 octahedra that share a cornercorner with one SnS4 tetrahedra, a cornercorner with one SnS5 trigonal bipyramid, a cornercorner with one SnS4 trigonal pyramid, an edgeedge with one CaS5 square pyramid, an edgeedge with one SnS4 tetrahedra, and an edgeedge with one SnS4 trigonal pyramid. There are a spread of Ca–S bond distances ranging from 2.88–2.95 Å. In the second Ca2+ site, Ca2+ is bonded to five S2- atoms to form distorted CaS5 square pyramids that share corners with three SnS4 tetrahedra, corners with two equivalent CaS5 trigonal bipyramids, an edgeedge with one CaS6 octahedra, and an edgeedge with one SnS5 trigonal bipyramid.
