Sc3Al is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Sc(1) is bonded to eight equivalent Sc(1) and four equivalent Al(1) atoms to form ScSc8Al4 cuboctahedra that share corners with twelve equivalent Sc(1)Sc8Al4 cuboctahedra, edges with eight equivalent Al(1)Sc12 cuboctahedra, edges with sixteen equivalent Sc(1)Sc8Al4 cuboctahedra, faces with four equivalent Al(1)Sc12 cuboctahedra, and faces with fourteen equivalent Sc(1)Sc8Al4 cuboctahedra. Al(1) is bonded to twelve equivalent Sc(1) atoms to form AlSc12 cuboctahedra that share corners with twelve equivalent Al(1)Sc12 cuboctahedra, edges with twenty-four equivalent Sc(1)Sc8Al4 cuboctahedra, faces with six equivalent Al(1)Sc12 cuboctahedra, and faces with twelve equivalent Sc(1)Sc8Al4 cuboctahedra.
