Title: Materials Data on Y3CuGeSe7 by Materials Project

Abstract

Y3CuGeSe7 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. Y3+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Y–Se bond distances ranging from 2.87–3.44 Å. Cu1+ is bonded in a trigonal planar geometry to three equivalent Se2- atoms. All Cu–Se bond lengths are 2.37 Å. Ge4+ 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. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Y3+ and one Ge4+ atom. In the second Se2- site, Se2- is bonded in a tetrahedral geometry to three equivalent Y3+ and one Ge4+ atom. In the third Se2- site, Se2- is bonded in a 5-coordinate geometry to four equivalent Y3+ and one Cu1+ atom.
