Title: Materials Data on Eu2GeSe4 by Materials Project

Abstract

Eu2GeSe4 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are two inequivalent Eu2+ sites. In the first Eu2+ site, Eu2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Eu–Se bond distances ranging from 3.08–3.72 Å. In the second Eu2+ site, Eu2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Eu–Se bond distances ranging from 3.08–3.70 Å. Ge4+ is bonded in a tetrahedral geometry to four Se2- atoms. All Ge–Se bond lengths are 2.39 Å. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to four Eu2+ and one Ge4+ atom to form a mixture of distorted corner, edge, and face-sharing SeEu4Ge square pyramids. In the second Se2- site, Se2- is bonded in a 3-coordinate geometry to four Eu2+ and one Ge4+ atom. In the third Se2- site, Se2- is bonded in a 3-coordinate geometry to four Eu2+ and one Ge4+ atom.
