Materials Data on Sm3Ru by Materials Project
Sm3Ru is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Sm sites. In the first Sm site, Sm is bonded in a 2-coordinate geometry to three equivalent Ru atoms. There are a spread of Sm–Ru bond distances ranging from 2.88–3.35 Å. In the second Sm site, Sm is bonded in a distorted bent 150 degrees geometry to two equivalent Ru atoms. There are one shorter (2.81 Å) and one longer (2.87 Å) Sm–Ru bond lengths. Ru is bonded in a 6-coordinate geometry to eight Sm atoms.
