Materials Data on Gd3Ge13Os4 by Materials Project
Gd3Os4Ge13 crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. Gd is bonded in a 8-coordinate geometry to four equivalent Os and twelve equivalent Ge atoms. All Gd–Os bond lengths are 3.21 Å. There are eight shorter (3.18 Å) and four longer (3.25 Å) Gd–Ge bond lengths. Os is bonded in a 6-coordinate geometry to three equivalent Gd and six equivalent Ge atoms. All Os–Ge bond lengths are 2.51 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 Os, and two Ge atoms. There are one shorter (2.66 Å) and one longer (3.06 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a cuboctahedral geometry to twelve equivalent Ge atoms.
