Nd7Ni3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 3-coordinate geometry to three equivalent Ni(1) atoms. In the second Nd site, Nd(3) is bonded in a distorted water-like geometry to two equivalent Ni(1) atoms. In the third Nd site, Nd(2) is bonded in a 3-coordinate geometry to three equivalent Ni(1) atoms. Ni(1) is bonded in a 6-coordinate geometry to one Nd(1), two equivalent Nd(3), and three equivalent Nd(2) atoms.
Nd7Ni3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 3-coordinate geometry to three equivalent Ni(1) atoms. All Nd(1)-Ni(1) bond lengths are 2.88 Å. In the second Nd site, Nd(3) is bonded in a distorted water-like geometry to two equivalent Ni(1) atoms. Both Nd(3)-Ni(1) bond lengths are 2.83 Å. In the third Nd site, Nd(2) is bonded in a 3-coordinate geometry to three equivalent Ni(1) atoms. There are two shorter (2.88 Å) and one longer (3.00 Å) Nd(2)-Ni(1) bond length. Ni(1) is bonded in a 6-coordinate geometry to one Nd(1), two equivalent Nd(3), and three equivalent Nd(2) atoms.
