Materials Data on Dy(FeGe)2 by Materials Project
DyFe2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Dy is bonded in a 8-coordinate geometry to eight equivalent Fe and eight equivalent Ge atoms. All Dy–Fe bond lengths are 3.23 Å. All Dy–Ge bond lengths are 3.10 Å. Fe is bonded to four equivalent Dy and four equivalent Ge atoms to form a mixture of distorted corner, edge, and face-sharing FeDy4Ge4 tetrahedra. All Fe–Ge bond lengths are 2.35 Å. Ge is bonded in a 9-coordinate geometry to four equivalent Dy, four equivalent Fe, and one Ge atom. The Ge–Ge bond length is 2.60 Å.
