ScNb crystallizes in the hexagonal P-6m2 space group. Sc(1) is bonded to six equivalent Sc(1) and six equivalent Nb(1) atoms to form ScSc6Nb6 cuboctahedra that share corners with eighteen equivalent Sc(1)Sc6Nb6 cuboctahedra, edges with six equivalent Sc(1)Sc6Nb6 cuboctahedra, edges with twelve equivalent Nb(1)Sc6Nb6 cuboctahedra, faces with eight equivalent Sc(1)Sc6Nb6 cuboctahedra, and faces with twelve equivalent Nb(1)Sc6Nb6 cuboctahedra. Nb(1) is bonded to six equivalent Sc(1) and six equivalent Nb(1) atoms to form NbSc6Nb6 cuboctahedra that share corners with eighteen equivalent Nb(1)Sc6Nb6 cuboctahedra, edges with six equivalent Nb(1)Sc6Nb6 cuboctahedra, edges with twelve equivalent Sc(1)Sc6Nb6 cuboctahedra, faces with eight equivalent Nb(1)Sc6Nb6 cuboctahedra, and faces with twelve equivalent Sc(1)Sc6Nb6 cuboctahedra.
