The crystal structure described by AlNd2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 5-coordinate geometry to five equivalent Al(1) atoms. In the second Nd site, Nd(2) is bonded in a 3-coordinate geometry to five equivalent Al(1) atoms. Al(1) is bonded in a 10-coordinate geometry to five equivalent Nd(1) and five equivalent Nd(2) atoms. is represented by the CIF card [CIF]
