The Materials Project

GdFe2Ge2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Gd is bonded in a 8-coordinate geometry to eight equivalent Fe and eight equivalent Ge atoms. There are a spread of Gd–Fe bond distances ranging from 3.30–3.37 Å. There are four shorter (3.08 Å) and four longer (3.09 Å) Gd–Ge bond lengths. Fe is bonded to four equivalent Gd and four equivalent Ge atoms to form a mixture of distorted edge, corner, and face-sharing FeGd4Ge4 tetrahedra. There are one shorter (2.43 Å) and three longer (2.44 Å) Fe–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to four equivalent Gd, four equivalent Fe, and one Ge atom. The Ge–Ge bond length is 2.54 Å.
