The compound described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
