Materials Data on Hf(FeGe)6 by Materials Project
HfFe6Ge6 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Hf is bonded to twelve equivalent Fe and eight Ge atoms to form distorted face-sharing HfFe12Ge8 hexagonal bipyramids. All Hf–Fe bond lengths are 3.23 Å. There are two shorter (2.76 Å) and six longer (2.92 Å) Hf–Ge bond lengths. Fe is bonded in a 12-coordinate geometry to two equivalent Hf, four equivalent Fe, and six Ge atoms. All Fe–Fe bond lengths are 2.53 Å. There are a spread of Fe–Ge bond distances ranging from 2.48–2.64 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to one Hf, six equivalent Fe, and one Ge atom. The Ge–Ge bond length is 2.55 Å. In the second Ge site, Ge is bonded in a 12-coordinate geometry to three equivalent Hf and six equivalent Fe atoms. In the third Ge site, Ge is bonded in a 6-coordinate geometry to six equivalent Fe atoms.
