Title: Materials Data on Dy6Ge3Se14 by Materials Project

Abstract

Dy6Ge3Se14 crystallizes in the trigonal P3 space group. The structure is three-dimensional. there are two inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Dy–Se bond distances ranging from 2.91–3.32 Å. In the second Dy3+ site, Dy3+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Dy–Se bond distances ranging from 2.89–3.30 Å. There are three inequivalent Ge+3.33+ sites. In the first Ge+3.33+ site, Ge+3.33+ is bonded in a tetrahedral geometry to four Se2- atoms. There are one shorter (2.36 Å) and three longer (2.41 Å) Ge–Se bond lengths. In the second Ge+3.33+ site, Ge+3.33+ is bonded in a tetrahedral geometry to four Se2- atoms. There are one shorter (2.37 Å) and three longer (2.40 Å) Ge–Se bond lengths. In the third Ge+3.33+ site, Ge+3.33+ is bonded in an octahedral geometry to six Se2- atoms. There are three shorter (2.77 Å) and three longer (2.83 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 Dy3+ and one Ge+3.33+ atom. In the second Se2-more » site, Se2- is bonded in a tetrahedral geometry to three equivalent Dy3+ and one Ge+3.33+ atom. In the third Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to three Dy3+ and one Ge+3.33+ atom. In the fourth Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to three Dy3+ and one Ge+3.33+ atom. In the fifth Se2- site, Se2- is bonded in a 5-coordinate geometry to four Dy3+ and one Ge+3.33+ atom. In the sixth Se2- site, Se2- is bonded in a 5-coordinate geometry to four Dy3+ and one Ge+3.33+ atom.« less
