The crystal structure described by NdZn5 crystallizes in the hexagonal P6/mmm space group. Nd(1) is bonded in a 18-coordinate geometry to six equivalent Zn(2) and twelve equivalent Zn(1) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded to four equivalent Nd(1), four equivalent Zn(1), and four equivalent Zn(2) atoms to form a mixture of face, corner, and edge-sharing ZnNd4Zn8 cuboctahedra. In the second Zn site, Zn(2) is bonded in a 9-coordinate geometry to three equivalent Nd(1) and six equivalent Zn(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
