Materials Data on Eu2ZnGe3 by Materials Project

Abstract

Eu2ZnGe3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Eu is bonded in a 12-coordinate geometry to three equivalent Zn and six Ge atoms. All Eu–Zn bond lengths are 3.28 Å. There are three shorter (3.08 Å) and three longer (3.28 Å) Eu–Ge bond lengths. Zn is bonded in a distorted trigonal planar geometry to six equivalent Eu and three equivalent Ge atoms. All Zn–Ge bond lengths are 2.48 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 6-coordinate geometry to three equivalent Eu and three equivalent Ge atoms. All Ge–Ge bond lengths are 2.63 Å. In the second Ge site, Ge is bonded in a distorted trigonal planar geometry to six equivalent Eu and three equivalent Zn atoms.
