Materials Data on CeGe3Ru by Materials Project

Abstract

CeRuGe3 crystallizes in the cubic Pm-3n space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 8-coordinate geometry to four equivalent Ru and twelve equivalent Ge atoms. All Ce–Ru bond lengths are 3.21 Å. There are eight shorter (3.09 Å) and four longer (3.22 Å) Ce–Ge bond lengths. In the second Ce site, Ce is bonded in a cuboctahedral geometry to twelve equivalent Ge atoms. All Ce–Ge bond lengths are 3.26 Å. Ru is bonded in a 9-coordinate geometry to three equivalent Ce and six equivalent Ge atoms. All Ru–Ge bond lengths are 2.53 Å. Ge is bonded in a 2-coordinate geometry to four Ce, two equivalent Ru, and three equivalent Ge atoms. There are one shorter (2.77 Å) and two longer (2.85 Å) Ge–Ge bond lengths.
