Materials Data on NaAc by Materials Project
NaAc crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Na is bonded to six equivalent Na and six equivalent Ac atoms to form NaNa6Ac6 cuboctahedra that share corners with eighteen equivalent NaNa6Ac6 cuboctahedra, edges with six equivalent NaNa6Ac6 cuboctahedra, edges with twelve equivalent AcNa6Ac6 cuboctahedra, faces with eight equivalent NaNa6Ac6 cuboctahedra, and faces with twelve equivalent AcNa6Ac6 cuboctahedra. All Na–Na bond lengths are 3.88 Å. All Na–Ac bond lengths are 3.96 Å.
