Materials Data on Ce2(Zn2Ge)3 by Materials Project

Abstract

Ce2(Zn2Ge)3 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. Ce is bonded in a 6-coordinate geometry to nine Zn and six equivalent Ge atoms. There are three shorter (3.25 Å) and six longer (3.45 Å) Ce–Zn bond lengths. All Ce–Ge bond lengths are 3.13 Å. There are two inequivalent Zn sites. In the first Zn site, Zn is bonded in a 3-coordinate geometry to four equivalent Ce, four equivalent Zn, and three equivalent Ge atoms. All Zn–Zn bond lengths are 2.80 Å. There are one shorter (2.53 Å) and two longer (2.67 Å) Zn–Ge bond lengths. In the second Zn site, Zn is bonded in a distorted water-like geometry to two equivalent Ce, six Zn, and two equivalent Ge atoms. Both Zn–Zn bond lengths are 2.53 Å. Both Zn–Ge bond lengths are 2.55 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Ce and five Zn atoms.
