Materials Data on Sm3Os by Materials Project
Sm3Os 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 Os atoms. There are a spread of Sm–Os bond distances ranging from 2.90–3.32 Å. In the second Sm site, Sm is bonded in a distorted bent 150 degrees geometry to two equivalent Os atoms. There are one shorter (2.84 Å) and one longer (2.89 Å) Sm–Os bond lengths. Os is bonded in a 6-coordinate geometry to eight Sm atoms.
