Materials Data on Yb2(Al3Ir)3 by Materials Project

Abstract

Yb2(IrAl3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Yb is bonded in a 11-coordinate geometry to eleven Al atoms. There are a spread of Yb–Al bond distances ranging from 3.07–3.14 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 8-coordinate geometry to eight Al atoms. There are a spread of Ir–Al bond distances ranging from 2.56–2.61 Å. In the second Ir site, Ir is bonded in a 8-coordinate geometry to eight Al atoms. There are two shorter (2.59 Å) and six longer (2.60 Å) Ir–Al bond lengths. There are four inequivalent Al sites. In the first Al site, Al is bonded in a 2-coordinate geometry to two equivalent Yb, two equivalent Ir, and six Al atoms. There are two shorter (2.74 Å) and four longer (2.79 Å) Al–Al bond lengths. In the second Al site, Al is bonded in a 3-coordinate geometry to three equivalent Yb, three Ir, and two Al atoms. The Al–Al bond length is 2.82 Å. In the third Al site, Al is bonded in a 3-coordinate geometry to two equivalent Yb, three Ir, and two equivalent Al atoms. Both Al–Al bond lengths are 2.91 Å. In the fourth Al site, Al is bonded in a 2-coordinate geometry to two equivalent Yb, two equivalent Ir, and six Al atoms. The Al–Al bond length is 2.74 Å.
