Materials Data on SmGeRu by Materials Project

SmRuGe crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sm is bonded in a 9-coordinate geometry to four equivalent Ru and six equivalent Ge atoms. There are two shorter (3.00 Å) and two longer (3.02 Å) Sm–Ru bond lengths. There are a spread of Sm–Ge bond distances ranging from 3.10–3.27 Å. Ru is bonded in a 8-coordinate geometry to four equivalent Sm and four equivalent Ge atoms. There are a spread of Ru–Ge bond distances ranging from 2.53–2.61 Å. Ge is bonded in a 10-coordinate geometry to six equivalent Sm and four equivalent Ru atoms.
