The structure described by NdPdSb crystallizes in the orthorhombic Pmma space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to eight equivalent Pd(1) and four equivalent Sb(1) atoms to form NdSb4Pd8 cuboctahedra that share edges with four equivalent Nd(1)Sb4Pd8 cuboctahedra, edges with eight equivalent Nd(2)Sb8Pd4 cuboctahedra, faces with four equivalent Nd(1)Sb4Pd8 cuboctahedra, and faces with four equivalent Nd(2)Sb8Pd4 cuboctahedra. In the second Nd site, Nd(2) is bonded to four equivalent Pd(1) and eight equivalent Sb(1) atoms to form NdSb8Pd4 cuboctahedra that share edges with four equivalent Nd(2)Sb8Pd4 cuboctahedra, edges with eight equivalent Nd(1)Sb4Pd8 cuboctahedra, faces with four equivalent Nd(1)Sb4Pd8 cuboctahedra, and faces with four equivalent Nd(2)Sb8Pd4 cuboctahedra. Pd(1) is bonded in a 9-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), one Pd(1), and two equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to two equivalent Nd(1), four equivalent Nd(2), two equivalent Pd(1), and one Sb(1) atom. is represented by the CIF file [CIF]
