Na3Hg crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded in a distorted see-saw-like geometry to four equivalent Hg(1) atoms. Hg(1) is bonded to twelve equivalent Na(1) atoms to form a mixture of corner and face-sharing HgNa12 cuboctahedra.
Na3Hg crystallizes in the hexagonal P6_3/mmc space group. Na(1) is bonded in a distorted see-saw-like geometry to four equivalent Hg(1) atoms. There are two shorter (3.32 Å) and two longer (3.47 Å) Na(1)-Hg(1) bond lengths. Hg(1) is bonded to twelve equivalent Na(1) atoms to form a mixture of corner and face-sharing HgNa12 cuboctahedra.
