Materials Data on Tm3Os by Materials Project
Tm3Os is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Tm sites. In the first Tm site, Tm is bonded in a distorted bent 150 degrees geometry to two equivalent Os atoms. There are one shorter (2.73 Å) and one longer (2.79 Å) Tm–Os bond lengths. In the second Tm site, Tm is bonded in a 3-coordinate geometry to three equivalent Os atoms. There are a spread of Tm–Os bond distances ranging from 2.84–3.10 Å. Os is bonded in a 8-coordinate geometry to eight Tm atoms.
