Materials Data on Cs3SnTe3 by Materials Project
Cs3SnTe3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are four inequivalent Cs1+ sites. In the first Cs1+ site, Cs1+ is bonded to six Te2- atoms to form distorted edge-sharing CsTe6 pentagonal pyramids. There are a spread of Cs–Te bond distances ranging from 3.79–4.10 Å. In the second Cs1+ site, Cs1+ is bonded in a 6-coordinate geometry to six Te2- atoms. There are a spread of Cs–Te bond distances ranging from 3.88–3.97 Å. In the third Cs1+ site, Cs1+ is bonded in a 7-coordinate geometry to seven Te2- atoms. There are a spread of Cs–Te bond distances ranging from 3.96–4.28 Å. In the fourth Cs1+ site, Cs1+ is bonded in a 6-coordinate geometry to six Te2- atoms. There are a spread of Cs–Te bond distances ranging from 3.82–4.40 Å. Sn3+ is bonded in a trigonal non-coplanar geometry to three Te2- atoms. There are a spread of Sn–Te bond distances ranging from 2.78–2.81 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 7-coordinate geometry to six Cs1+ and one Sn3+ atom. In the second Te2- site, Te2- is bonded in a 7-coordinate geometry to six Cs1+ and one Sn3+ atom. In the third Te2- site, Te2- is bonded in a 8-coordinate geometry to seven Cs1+ and one Sn3+ atom.
