Materials Data on Yb(Al5Os)2 by Materials Project

Abstract

Yb(OsAl5)2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Yb is bonded in a 10-coordinate geometry to four equivalent Os and fourteen Al atoms. All Yb–Os bond lengths are 3.48 Å. There are a spread of Yb–Al bond distances ranging from 3.18–3.34 Å. Os is bonded in a 10-coordinate geometry to two equivalent Yb and ten Al atoms. There are a spread of Os–Al bond distances ranging from 2.58–2.75 Å. There are five inequivalent Al sites. In the first Al site, Al is bonded in a 12-coordinate geometry to one Yb, two equivalent Os, and nine Al atoms. There are a spread of Al–Al bond distances ranging from 2.67–3.04 Å. In the second Al site, Al is bonded in a 2-coordinate geometry to one Yb, two equivalent Os, and three Al atoms. The Al–Al bond length is 2.63 Å. In the third Al site, Al is bonded in a distorted bent 120 degrees geometry to one Yb, two equivalent Os, and four Al atoms. Both Al–Al bond lengths are 2.93 Å. In the fourth Al site, Al is bonded in a 2-coordinate geometry to two equivalent Yb, two equivalent Os, and eight Al atoms. There are one shorter (2.75 Å) and two longer (2.76 Å) Al–Al bond lengths. In the fifth Al site, Al is bonded in a distorted linear geometry to two equivalent Yb, two equivalent Os, and four Al atoms.
