Materials Data on YAl3Ni2 by Materials Project
YNi2Al3 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. there are two inequivalent Y sites. In the first Y site, Y is bonded in a 6-coordinate geometry to six equivalent Ni and twelve Al atoms. All Y–Ni bond lengths are 3.12 Å. There are six shorter (3.18 Å) and six longer (3.31 Å) Y–Al bond lengths. In the second Y site, Y is bonded in a hexagonal planar geometry to six equivalent Ni atoms. All Y–Ni bond lengths are 2.84 Å. Ni is bonded in a 9-coordinate geometry to three Y and six Al atoms. All Ni–Al bond lengths are 2.49 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded in a 12-coordinate geometry to two equivalent Y and four equivalent Ni atoms. In the second Al site, Al is bonded in a 12-coordinate geometry to four equivalent Y and four equivalent Ni atoms.
