Materials Data on Dy(Fe2Ge)2 by Materials Project

DyFe4Ge2 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Dy is bonded in a 6-coordinate geometry to twelve equivalent Fe and six equivalent Ge atoms. There are four shorter (3.15 Å) and eight longer (3.30 Å) Dy–Fe bond lengths. All Dy–Ge bond lengths are 2.93 Å. Fe is bonded in a 3-coordinate geometry to three equivalent Dy and three equivalent Ge atoms. All Fe–Ge bond lengths are 2.45 Å. Ge is bonded in a 9-coordinate geometry to three equivalent Dy and six equivalent Fe atoms.

Materials Data on DyFeGe2 by Materials Project

DyFeGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Dy is bonded in a 8-coordinate geometry to four equivalent Fe and ten Ge atoms. All Dy–Fe bond lengths are 3.26 Å. There are a spread of Dy–Ge bond distances ranging from 3.10–3.22 Å. Fe is bonded in a 5-coordinate geometry to four equivalent Dy and five Ge atoms. There are a spread of Fe–Ge bond distances ranging from 2.29–2.39 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Dy, one Fe, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.59 Å. In the second Ge site, Ge is bonded in a 4-coordinate geometry to four equivalent Dy and four equivalent Fe atoms.
