In the first Fe site, Fe(1) is bonded to two equivalent Nd(1), one V(1), one V(2), one Fe(2), two equivalent Fe(1), one Co(2), two equivalent Co(1), and two equivalent Co(3) atoms to form distorted FeNd2V2Fe3Co5 cuboctahedra that share corners with two equivalent Fe(2)Nd2V2Fe4Co4 cuboctahedra, corners with ten equivalent Fe(1)Nd2V2Fe3Co5 cuboctahedra,  an edgeedge with one Fe(2)Nd2V2Fe4Co4 cuboctahedra, edges with four equivalent Fe(1)Nd2V2Fe3Co5 cuboctahedra, faces with two equivalent Fe(2)Nd2V2Fe4Co4 cuboctahedra, and faces with six equivalent Fe(1)Nd2V2Fe3Co5 cuboctahedra. In the second Fe site, Fe(2) is bonded to two equivalent Nd(1), two equivalent V(1), four equivalent Fe(1), two equivalent Co(1), and two equivalent Co(3) atoms to form distorted FeNd2V2Fe4Co4 cuboctahedra that share corners with eight equivalent Fe(1)Nd2V2Fe3Co5 cuboctahedra, edges with two equivalent Fe(2)Nd2V2Fe4Co4 cuboctahedra, edges with four equivalent Fe(1)Nd2V2Fe3Co5 cuboctahedra, and faces with eight equivalent Fe(1)Nd2V2Fe3Co5 cuboctahedra. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 12-coordinate geometry to two equivalent Nd(1), one V(1), one V(2), one Fe(2), four equivalent Fe(1), one Co(2), and two equivalent Co(3) atoms. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to two equivalent Nd(1), two equivalent V(2), four equivalent Fe(1), two equivalent Co(1), and two equivalent Co(3) atoms. In the third Co site, Co(3) is bonded in a 14-coordinate geometry to one Nd(1), two equivalent V(1), two equivalent V(2), one Fe(2), four equivalent Fe(1), one Co(2), one Co(3), and two equivalent Co(1) atoms. is represented by the CIF file [CIF]
