Materials Data on Pr3Os by Materials Project
Pr3Os is Cementite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 2-coordinate geometry to three equivalent Os atoms. There are a spread of Pr–Os bond distances ranging from 2.93–3.46 Å. In the second Pr site, Pr is bonded in a bent 150 degrees geometry to two equivalent Os atoms. There are one shorter (2.89 Å) and one longer (2.94 Å) Pr–Os bond lengths. Os is bonded in a 6-coordinate geometry to eight Pr atoms.
