Materials Data on HoAl3Ni2 by Materials Project
Ni2Al3Ho crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. there are two inequivalent Ho sites. In the first Ho site, Ho is bonded in a 6-coordinate geometry to six equivalent Ni and twelve Al atoms. All Ho–Ni bond lengths are 3.10 Å. There are six shorter (3.16 Å) and six longer (3.27 Å) Ho–Al bond lengths. In the second Ho site, Ho is bonded in a hexagonal planar geometry to six equivalent Ni atoms. All Ho–Ni bond lengths are 2.81 Å. Ni is bonded in a 9-coordinate geometry to three Ho and six Al atoms. There are four shorter (2.46 Å) and two longer (2.48 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 Ho and four equivalent Ni atoms. In the second Al site, Al is bonded in a 12-coordinate geometry to two equivalent Ho and four equivalent Ni atoms.
