NaTm is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Na(1) is bonded to six equivalent Na(1) and six equivalent Tm(1) atoms to form NaNa6Tm6 cuboctahedra that share corners with eighteen equivalent Na(1)Na6Tm6 cuboctahedra, edges with six equivalent Na(1)Na6Tm6 cuboctahedra, edges with twelve equivalent Tm(1)Na6Tm6 cuboctahedra, faces with eight equivalent Na(1)Na6Tm6 cuboctahedra, and faces with twelve equivalent Tm(1)Na6Tm6 cuboctahedra. Tm(1) is bonded to six equivalent Na(1) and six equivalent Tm(1) atoms to form TmNa6Tm6 cuboctahedra that share corners with eighteen equivalent Tm(1)Na6Tm6 cuboctahedra, edges with six equivalent Tm(1)Na6Tm6 cuboctahedra, edges with twelve equivalent Na(1)Na6Tm6 cuboctahedra, faces with eight equivalent Tm(1)Na6Tm6 cuboctahedra, and faces with twelve equivalent Na(1)Na6Tm6 cuboctahedra.
