NdSc3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Nd(1) is bonded to twelve Sc(1,1) atoms to form NdSc12 cuboctahedra that share corners with six equivalent Nd(1)Sc12 cuboctahedra; corners with twelve equivalent Sc(1)Nd4Sc8 cuboctahedra; edges with eighteen Sc(1,1)Nd4Sc8 cuboctahedra; faces with eight equivalent Nd(1)Sc12 cuboctahedra; and faces with twelve Sc(1,1)Nd4Sc8 cuboctahedra. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded to four equivalent Nd(1) and eight equivalent Sc(1) atoms to form distorted ScNd4Sc8 cuboctahedra that share corners with four equivalent Nd(1)Sc12 cuboctahedra; corners with fourteen Sc(1,1)Nd4Sc8 cuboctahedra; edges with six equivalent Nd(1)Sc12 cuboctahedra; edges with twelve equivalent Sc(1)Nd4Sc8 cuboctahedra; faces with four equivalent Nd(1)Sc12 cuboctahedra; and faces with sixteen Sc(1,1)Nd4Sc8 cuboctahedra. In the second Sc site, Sc(1) is bonded to four equivalent Nd(1) and eight Sc(1,1) atoms to form distorted ScNd4Sc8 cuboctahedra that share corners with four equivalent Nd(1)Sc12 cuboctahedra; corners with fourteen Sc(1,1)Nd4Sc8 cuboctahedra; edges with six equivalent Nd(1)Sc12 cuboctahedra; edges with twelve Sc(1,1)Nd4Sc8 cuboctahedra; faces with four equivalent Nd(1)Sc12 cuboctahedra; and faces with sixteen Sc(1,1)Nd4Sc8 cuboctahedra.
