Materials Data on Ho(Fe2Ge)2 by Materials Project
HoFe4Ge2 crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Ho is bonded in a 6-coordinate geometry to twelve equivalent Fe and six equivalent Ge atoms. There are four shorter (3.17 Å) and eight longer (3.27 Å) Ho–Fe bond lengths. There are two shorter (2.91 Å) and four longer (2.94 Å) Ho–Ge bond lengths. Fe is bonded in a 3-coordinate geometry to three equivalent Ho and three equivalent Ge atoms. There are one shorter (2.43 Å) and two longer (2.44 Å) Fe–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to three equivalent Ho and six equivalent Fe atoms.
