Materials Data on ErAl3Ni2 by Materials Project
ErNi2Al3 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. there are two inequivalent Er sites. In the first Er site, Er is bonded in a 6-coordinate geometry to six equivalent Ni and twelve Al atoms. All Er–Ni bond lengths are 3.11 Å. There are six shorter (3.16 Å) and six longer (3.29 Å) Er–Al bond lengths. In the second Er site, Er is bonded in a hexagonal planar geometry to six equivalent Ni atoms. All Er–Ni bond lengths are 2.82 Å. Ni is bonded in a 9-coordinate geometry to three Er and six Al atoms. There are two shorter (2.48 Å) and four longer (2.49 Å) Ni–Al bond lengths. There are two inequivalent Al sites. In the first Al site, Al is bonded in a 12-coordinate geometry to four equivalent Er and four equivalent Ni atoms. In the second Al site, Al is bonded in a 12-coordinate geometry to two equivalent Er and four equivalent Ni atoms.
