Materials Data on Tb3Os by Materials Project
Tb3Os is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded in a 3-coordinate geometry to three equivalent Os atoms. There are a spread of Tb–Os bond distances ranging from 2.86–3.20 Å. In the second Tb site, Tb is bonded in a distorted bent 150 degrees geometry to two equivalent Os atoms. There are one shorter (2.79 Å) and one longer (2.85 Å) Tb–Os bond lengths. Os is bonded in a 8-coordinate geometry to eight Tb atoms.
