Materials Data on Ca3Sn4S11 by Materials Project
Abstract
Ca3Sn4S11 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 2.82–3.27 Å. In the second Ca2+ site, Ca2+ is bonded to seven S2- atoms to form distorted CaS7 pentagonal bipyramids that share corners with two equivalent SnS6 octahedra and an edgeedge with one CaS7 pentagonal bipyramid. The corner-sharing octahedra tilt angles range from 31–62°. There are a spread of Ca–S bond distances ranging from 2.84–3.06 Å. In the third 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 2.75–3.11 Å. There are four inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded in a 4-coordinate geometry to four S2- atoms. There are a spread of Sn–S bond distances ranging from 2.51–2.98 Å. In the second Sn4+ site, Sn4+ is bonded in a 1-coordinate geometry to seven S2- atoms. There are a spread of Sn–S bond distances ranging from 2.57–3.30 Å. In the third Sn4+ site, Sn4+ is bonded to sixmore »
