NdCo1 crystallizes in the monoclinic C2/m space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 7-coordinate geometry to one Co(1) and six equivalent Co(2) atoms. In the second Nd site, Nd(2) is bonded in a 4-coordinate geometry to three equivalent Co(1) and six equivalent Co(2) atoms. In the third Nd site, Nd(3) is bonded in a distorted square co-planar geometry to four equivalent Co(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent Nd(1), six equivalent Nd(2), and four equivalent Co(2) atoms to form edge-sharing CoNd8Co4 cuboctahedra. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to one Nd(3), three equivalent Nd(1), three equivalent Nd(2), one Co(1), and one Co(2) atom.
NdCo1 crystallizes in the monoclinic C2/m space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 7-coordinate geometry to one Co(1) and six equivalent Co(2) atoms. The Nd(1)-Co(1) bond length is 3.18 Å. There are a spread of Nd(1)-Co(2) bond distances ranging from 3.02-3.19 Å. In the second Nd site, Nd(2) is bonded in a 4-coordinate geometry to three equivalent Co(1) and six equivalent Co(2) atoms. There are two shorter (3.34 Å) and one longer (3.40 Å) Nd(2)-Co(1) bond length. There are a spread of Nd(2)-Co(2) bond distances ranging from 2.91-3.33 Å. In the third Nd site, Nd(3) is bonded in a distorted square co-planar geometry to four equivalent Co(2) atoms. All Nd(3)-Co(2) bond lengths are 2.74 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent Nd(1), six equivalent Nd(2), and four equivalent Co(2) atoms to form edge-sharing CoNd8Co4 cuboctahedra.
