Materials Data on Y3Os by Materials Project
Y3Os is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 3-coordinate geometry to three equivalent Os atoms. There are a spread of Y–Os bond distances ranging from 2.88–3.18 Å. In the second Y site, Y is bonded in a distorted bent 150 degrees geometry to two equivalent Os atoms. There are one shorter (2.77 Å) and one longer (2.84 Å) Y–Os bond lengths. Os is bonded in a 8-coordinate geometry to eight Y atoms.
