Materials Data on Dy2(Al3Ir)3 by Materials Project

Abstract

Dy2(IrAl3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Dy is bonded in a 11-coordinate geometry to six Ir and eleven Al atoms. There are a spread of Dy–Ir bond distances ranging from 3.43–3.47 Å. There are a spread of Dy–Al bond distances ranging from 3.05–3.15 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 8-coordinate geometry to four equivalent Dy and eight Al atoms. There are four shorter (2.57 Å) and four longer (2.62 Å) Ir–Al bond lengths. In the second Ir site, Ir is bonded in a 8-coordinate geometry to four equivalent Dy and eight Al atoms. There are a spread of Ir–Al bond distances ranging from 2.56–2.61 Å. There are four inequivalent Al sites. In the first Al site, Al is bonded in a 2-coordinate geometry to two equivalent Dy and two equivalent Ir atoms. In the second Al site, Al is bonded in a 3-coordinate geometry to three equivalent Dy and three Ir atoms. In the third Al site, Al is bonded in a 3-coordinate geometry to two equivalent Dy and three Ir atoms. In the fourth Al site, Al is bonded in a 2-coordinate geometry to two equivalent Dy and two equivalent Ir atoms.
