Title: Materials Data on Sm6Ge3Se14 by Materials Project

Abstract

Sm6Ge3Se14 crystallizes in the trigonal P3 space group. The structure is three-dimensional. there are two inequivalent Sm+2.67+ sites. In the first Sm+2.67+ site, Sm+2.67+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Sm–Se bond distances ranging from 2.97–3.30 Å. In the second Sm+2.67+ site, Sm+2.67+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Sm–Se bond distances ranging from 2.95–3.28 Å. There are three inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded in a tetrahedral geometry to four Se2- atoms. There are one shorter (2.35 Å) and three longer (2.41 Å) Ge–Se bond lengths. In the second Ge4+ site, Ge4+ is bonded in a tetrahedral geometry to four Se2- atoms. There are one shorter (2.35 Å) and three longer (2.41 Å) Ge–Se bond lengths. In the third Ge4+ site, Ge4+ is bonded in an octahedral geometry to six Se2- atoms. There are three shorter (2.80 Å) and three longer (2.85 Å) Ge–Se bond lengths. There are six inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a tetrahedral geometry to three equivalent Sm+2.67+ and one Ge4+ atom. In the second Se2-more » site, Se2- is bonded in a tetrahedral geometry to three equivalent Sm+2.67+ and one Ge4+ atom. In the third Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to three Sm+2.67+ and one Ge4+ atom. In the fourth Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to three Sm+2.67+ and one Ge4+ atom. In the fifth Se2- site, Se2- is bonded in a 5-coordinate geometry to four Sm+2.67+ and one Ge4+ atom. In the sixth Se2- site, Se2- is bonded in a 5-coordinate geometry to four Sm+2.67+ and one Ge4+ atom.« less
