The structure described by Nd3Sc is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Nd(1) is bonded to eight equivalent Nd(1) and four equivalent Sc(1) atoms to form distorted NdNd8Sc4 cuboctahedra that share corners with four equivalent Sc(1)Nd12 cuboctahedra, corners with fourteen equivalent Nd(1)Nd8Sc4 cuboctahedra, edges with six equivalent Sc(1)Nd12 cuboctahedra, edges with twelve equivalent Nd(1)Nd8Sc4 cuboctahedra, faces with four equivalent Sc(1)Nd12 cuboctahedra, and faces with sixteen equivalent Nd(1)Nd8Sc4 cuboctahedra. Sc(1) is bonded to twelve equivalent Nd(1) atoms to form ScNd12 cuboctahedra that share corners with six equivalent Sc(1)Nd12 cuboctahedra, corners with twelve equivalent Nd(1)Nd8Sc4 cuboctahedra, edges with eighteen equivalent Nd(1)Nd8Sc4 cuboctahedra, faces with eight equivalent Sc(1)Nd12 cuboctahedra, and faces with twelve equivalent Nd(1)Nd8Sc4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
