Materials Data on La3AgSnS7 by Materials Project
La3AgSnS7 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. La3+ is bonded in a 8-coordinate geometry to eight S2- atoms. There are a spread of La–S bond distances ranging from 2.94–3.31 Å. Ag1+ is bonded in a trigonal planar geometry to three equivalent S2- atoms. All Ag–S bond lengths are 2.47 Å. Sn4+ is bonded in a tetrahedral geometry to four S2- atoms. There are one shorter (2.38 Å) and three longer (2.43 Å) Sn–S bond lengths. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to four equivalent La3+ and one Ag1+ atom. In the second S2- site, S2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent La3+ and one Sn4+ atom. In the third S2- site, S2- is bonded in a tetrahedral geometry to three equivalent La3+ and one Sn4+ atom.
