Materials Data on SmAl4 by Materials Project
Abstract
Al4Sm crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Sm is bonded in a 1-coordinate geometry to thirteen Al atoms. There are a spread of Sm–Al bond distances ranging from 3.12–3.20 Å. There are three inequivalent Al sites. In the first Al site, Al is bonded in a 10-coordinate geometry to three equivalent Sm and seven Al atoms. There are a spread of Al–Al bond distances ranging from 2.65–2.93 Å. In the second Al site, Al is bonded in a 6-coordinate geometry to four equivalent Sm and two equivalent Al atoms. In the third Al site, Al is bonded in a 3-coordinate geometry to three equivalent Sm and six equivalent Al atoms.
