Materials Data on La3AgSnSe7 by Materials Project
Abstract
La3AgSnSe7 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. La3+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of La–Se bond distances ranging from 3.06–3.42 Å. Ag1+ is bonded in a trigonal planar geometry to three equivalent Se2- atoms. All Ag–Se bond lengths are 2.59 Å. Sn4+ is bonded in a tetrahedral geometry to four Se2- atoms. There are one shorter (2.52 Å) and three longer (2.58 Å) Sn–Se bond lengths. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a tetrahedral geometry to three equivalent La3+ and one Sn4+ atom. In the second Se2- site, Se2- is bonded in a 5-coordinate geometry to four equivalent La3+ and one Ag1+ atom. In the third Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent La3+ and one Sn4+ atom.
