Materials Data on SmAl4Ni by Materials Project
SmNiAl4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sm is bonded in a 9-coordinate geometry to two equivalent Ni and thirteen Al atoms. Both Sm–Ni bond lengths are 3.24 Å. There are a spread of Sm–Al bond distances ranging from 3.02–3.35 Å. Ni is bonded in a 7-coordinate geometry to two equivalent Sm and seven Al atoms. There are a spread of Ni–Al bond distances ranging from 2.31–2.49 Å. There are three inequivalent Al sites. In the first Al site, Al is bonded in a 10-coordinate geometry to four equivalent Sm and six Al atoms. There are four shorter (2.90 Å) and two longer (3.00 Å) Al–Al bond lengths. In the second Al site, Al is bonded in a distorted single-bond geometry to three equivalent Sm, one Ni, and four equivalent Al atoms. In the third Al site, Al is bonded in a 3-coordinate geometry to three equivalent Sm, three equivalent Ni, and one Al atom.
