Materials Data on NaTm by Materials Project
NaTm is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Na is bonded to six equivalent Na and six equivalent Tm atoms to form NaNa6Tm6 cuboctahedra that share corners with eighteen equivalent NaNa6Tm6 cuboctahedra, edges with six equivalent NaNa6Tm6 cuboctahedra, edges with twelve equivalent TmNa6Tm6 cuboctahedra, faces with eight equivalent NaNa6Tm6 cuboctahedra, and faces with twelve equivalent TmNa6Tm6 cuboctahedra. All Na–Na bond lengths are 3.43 Å. All Na–Tm bond lengths are 3.69 Å.
