Materials Data on Gd2(Al3Rh)3 by Materials Project

Abstract

Gd2(RhAl3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Gd is bonded in a 11-coordinate geometry to eleven Al atoms. There are a spread of Gd–Al bond distances ranging from 3.06–3.14 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 8-coordinate geometry to eight Al atoms. There are four shorter (2.57 Å) and four longer (2.62 Å) Rh–Al bond lengths. In the second Rh site, Rh is bonded in a 8-coordinate geometry to eight Al atoms. There are a spread of Rh–Al bond distances ranging from 2.56–2.62 Å. There are four inequivalent Al sites. In the first Al site, Al is bonded in a 2-coordinate geometry to two equivalent Gd and two equivalent Rh atoms. In the second Al site, Al is bonded in a 3-coordinate geometry to three equivalent Gd and three Rh atoms. In the third Al site, Al is bonded in a 3-coordinate geometry to two equivalent Gd and three Rh atoms. In the fourth Al site, Al is bonded in a 2-coordinate geometry to two equivalent Gd and two equivalent Rh atoms.
