Materials Data on Gd(CuGe)2 by Materials Project

Abstract

GdCu2Ge2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Gd is bonded in a 4-coordinate geometry to eight equivalent Cu and eight equivalent Ge atoms. There are a spread of Gd–Cu bond distances ranging from 3.23–3.36 Å. There are four shorter (3.12 Å) and four longer (3.20 Å) Gd–Ge bond lengths. Cu is bonded in a 4-coordinate geometry to four equivalent Gd and four equivalent Ge atoms. There are three shorter (2.45 Å) and one longer (2.46 Å) Cu–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to four equivalent Gd, four equivalent Cu, and one Ge atom. The Ge–Ge bond length is 2.49 Å.
