Materials Data on Pr3Ge13Ru4 by Materials Project

Abstract

Pr3Ru4Ge13 crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. Pr is bonded in a 12-coordinate geometry to four equivalent Ru and twelve equivalent Ge atoms. All Pr–Ru bond lengths are 3.24 Å. There are eight shorter (3.25 Å) and four longer (3.27 Å) Pr–Ge bond lengths. Ru is bonded in a 6-coordinate geometry to three equivalent Pr and six equivalent Ge atoms. All Ru–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 Pr, two equivalent Ru, and one Ge atom. The Ge–Ge bond length is 3.03 Å. In the second Ge site, Ge is bonded in a cuboctahedral geometry to twelve equivalent Ge atoms.
