Materials Data on Gd3Co4Ge13 by Materials Project

Abstract

Gd3Co4Ge13 crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. Gd is bonded in a 12-coordinate geometry to four equivalent Co and twelve equivalent Ge atoms. All Gd–Co bond lengths are 3.10 Å. All Gd–Ge bond lengths are 3.09 Å. Co is bonded in a 6-coordinate geometry to three equivalent Gd and six equivalent Ge atoms. All Co–Ge bond lengths are 2.41 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to three equivalent Gd, two equivalent Co, and four Ge atoms. There are a spread of Ge–Ge bond distances ranging from 2.69–3.00 Å. In the second Ge site, Ge is bonded in a cuboctahedral geometry to twelve equivalent Ge atoms.
