Materials Data on Nd7Ni3 by Materials Project
Nd7Ni3 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are three inequivalent Nd sites. In the first Nd site, Nd is bonded in a 3-coordinate geometry to three equivalent Ni atoms. All Nd–Ni bond lengths are 2.88 Å. In the second Nd site, Nd is bonded in a distorted water-like geometry to two equivalent Ni atoms. Both Nd–Ni bond lengths are 2.83 Å. In the third Nd site, Nd is bonded in a 3-coordinate geometry to three equivalent Ni atoms. There are two shorter (2.88 Å) and one longer (3.00 Å) Nd–Ni bond lengths. Ni is bonded in a 6-coordinate geometry to six Nd atoms.
