Abstract

Fe6Ge6Ho crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ho is bonded to twelve Fe and eight Ge atoms to form distorted HoFe12Ge8 hexagonal bipyramids that share corners with four equivalent HoFe12Ge8 hexagonal bipyramids, faces with eight equivalent FeHo2Fe4Ge6 cuboctahedra, and faces with four equivalent HoFe12Ge8 hexagonal bipyramids. There are a spread of Ho–Fe bond distances ranging from 3.25–3.28 Å. There are a spread of Ho–Ge bond distances ranging from 2.82–2.98 Å. There are three inequivalent Fe sites. In the first Fe site, Fe is bonded to two equivalent Ho, four Fe, and six Ge atoms to form distorted FeHo2Fe4Ge6 cuboctahedra that share corners with four equivalent FeHo2Fe4Ge6 cuboctahedra, edges with two equivalent FeHo2Fe4Ge6 cuboctahedra, faces with four equivalent FeHo2Fe4Ge6 cuboctahedra, and faces with four equivalent HoFe12Ge8 hexagonal bipyramids. All Fe–Fe bond lengths are 2.55 Å. There are a spread of Fe–Ge bond distances ranging from 2.50–2.68 Å. In the second Fe site, Fe is bonded in a 12-coordinate geometry to two equivalent Ho, four Fe, and six Ge atoms. All Fe–Fe bond lengths are 2.55 Å. There are four shorter (2.51 Å) and two longer (2.66 Å) Fe–Ge bond lengths. In the third Fe site, Femore »« less
