Na3Os crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded in a distorted see-saw-like geometry to four equivalent Os(1) atoms. Os(1) is bonded to twelve equivalent Na(1) atoms to form a mixture of face and corner-sharing OsNa12 cuboctahedra.
Na3Os crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded in a distorted see-saw-like geometry to four equivalent Os(1) atoms. There are two shorter (3.16 Å) and two longer (3.22 Å) Na(1)-Os(1) bond lengths. Os(1) is bonded to twelve equivalent Na(1) atoms to form a mixture of face and corner-sharing OsNa12 cuboctahedra.
