The structure described by Nd3Al crystallizes in the hexagonal P6_3/mmc space group. Nd(1) is bonded in a 12-coordinate geometry to eight equivalent Nd(1) and four equivalent Al(1) atoms. Al(1) is bonded to twelve equivalent Nd(1) atoms to form a mixture of face and corner-sharing AlNd12 cuboctahedra. is represented by the CIF card [CIF]
