Materials Data on Y2(Al3Rh)3 by Materials Project

Abstract

Y2(RhAl3)3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Y is bonded in a 11-coordinate geometry to six Rh and eleven Al atoms. There are a spread of Y–Rh bond distances ranging from 3.43–3.47 Å. There are a spread of Y–Al bond distances ranging from 3.06–3.15 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 8-coordinate geometry to four equivalent Y and 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 four equivalent Y and 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 Y and two equivalent Rh atoms. In the second Al site, Al is bonded in a 3-coordinate geometry to three equivalent Y and three Rh atoms. In the third Al site, Al is bonded in a 3-coordinate geometry to two equivalent Y and three Rh atoms. In the fourth Al site, Al is bonded in a 2-coordinate geometry to two equivalent Y and two equivalent Rh atoms.
