Na3Sc is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Na(1) is bonded to eight equivalent Na(1) and four equivalent Sc(1) atoms to form distorted NaNa8Sc4 cuboctahedra that share corners with twelve equivalent Na(1)Na8Sc4 cuboctahedra, edges with eight equivalent Sc(1)Na12 cuboctahedra, edges with sixteen equivalent Na(1)Na8Sc4 cuboctahedra, faces with four equivalent Sc(1)Na12 cuboctahedra, and faces with fourteen equivalent Na(1)Na8Sc4 cuboctahedra. Sc(1) is bonded to twelve equivalent Na(1) atoms to form ScNa12 cuboctahedra that share corners with twelve equivalent Sc(1)Na12 cuboctahedra, edges with twenty-four equivalent Na(1)Na8Sc4 cuboctahedra, faces with six equivalent Sc(1)Na12 cuboctahedra, and faces with twelve equivalent Na(1)Na8Sc4 cuboctahedra.
