Materials Data on CaSnS3 by Materials Project
Abstract
CaSnS3 is Esseneite-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of Ca–S bond distances ranging from 2.92–3.25 Å. In the second Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of Ca–S bond distances ranging from 2.79–3.47 Å. In the third Ca2+ site, Ca2+ is bonded to six S2- atoms to form distorted CaS6 octahedra that share corners with six SnS4 tetrahedra and an edgeedge with one CaS6 octahedra. There are a spread of Ca–S bond distances ranging from 2.86–3.00 Å. There are three inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to four S2- atoms to form SnS4 tetrahedra that share corners with two equivalent CaS6 octahedra and corners with two SnS4 tetrahedra. The corner-sharing octahedra tilt angles range from 67–70°. There are a spread of Sn–S bond distances ranging from 2.38–2.43 Å. In the second Sn4+ site, Sn4+ is bonded to four S2- atoms to form SnS4 tetrahedra that share a cornercorner with one CaS6more »

In the seventh S2- site, S2- is bonded in a 3-coordinate geometry to three Ca2+ and one Sn4+ atom. In the eighth S2- site, S2- is bonded to three Ca2+ and one Sn4+ atom to form a mixture of distorted corner and edge-sharing SCa3Sn tetrahedra.
