The structure described by NdPdAl crystallizes in the hexagonal P-62m space group. Nd(1) is bonded in a 5-coordinate geometry to one Pd(1) and four equivalent Pd(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to three equivalent Nd(1) and six equivalent Al(1) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to six equivalent Nd(1) and three equivalent Al(1) atoms. Al(1) is bonded in a 4-coordinate geometry to two equivalent Pd(1) and two equivalent Pd(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
