Nd7Co3 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 Co(1) atoms. In the second Nd site, Nd(3) is bonded in a 3-coordinate geometry to four equivalent Co(1) atoms. In the third Nd site, Nd(2) is bonded in a distorted water-like geometry to four equivalent Co(1) atoms. Co(1) is bonded in a 9-coordinate geometry to one Nd(1), four equivalent Nd(2), and four equivalent Nd(3) atoms.
Nd7Co3 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 Co(1) atoms. All Nd(1)-Co(1) bond lengths are 2.84 Å. In the second Nd site, Nd(3) is bonded in a 3-coordinate geometry to four equivalent Co(1) atoms. There are a spread of Nd(3)-Co(1) bond distances ranging from 2.78-3.58 Å. In the third Nd site, Nd(2) is bonded in a distorted water-like geometry to four equivalent Co(1) atoms. There are two shorter (2.77 Å) and two longer (3.53 Å) Nd(2)-Co(1) bond lengths. Co(1) is bonded in a 9-coordinate geometry to one Nd(1), four equivalent Nd(2), and four equivalent Nd(3) atoms.
