Abstract
DyFe6Ge6 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Dy is bonded to twelve Fe and eight Ge atoms to form distorted DyFe12Ge8 hexagonal bipyramids that share corners with four equivalent DyFe12Ge8 hexagonal bipyramids, faces with eight equivalent FeDy2Fe4Ge6 cuboctahedra, and faces with four equivalent DyFe12Ge8 hexagonal bipyramids. There are a spread of Dy–Fe bond distances ranging from 3.24–3.29 Å. There are a spread of Dy–Ge bond distances ranging from 2.82–2.99 Å. There are three inequivalent Fe sites. In the first Fe site, Fe is bonded to two equivalent Dy, four Fe, and six Ge atoms to form distorted FeDy2Fe4Ge6 cuboctahedra that share corners with four equivalent FeDy2Fe4Ge6 cuboctahedra, edges with two equivalent FeDy2Fe4Ge6 cuboctahedra, faces with four equivalent FeDy2Fe4Ge6 cuboctahedra, and faces with four equivalent DyFe12Ge8 hexagonal bipyramids. There are two shorter (2.55 Å) and two longer (2.57 Å) Fe–Fe bond lengths. There are a spread of Fe–Ge bond distances ranging from 2.51–2.68 Å. In the second Fe site, Fe is bonded in a 12-coordinate geometry to two equivalent Dy, four Fe, and six Ge atoms. There are two shorter (2.55 Å) and two longer (2.57 Å) Fe–Fe bond lengths. There are a spread of Fe–Gemore »
