Materials Data on Na2SnHg by Materials Project
NaHgNaSn is Zintl Phase-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional and consists of one NaHg framework and one NaSn framework. In the NaHg framework, Na is bonded to four equivalent Hg atoms to form distorted corner-sharing NaHg4 tetrahedra. All Na–Hg bond lengths are 3.20 Å. Hg is bonded to four equivalent Na atoms to form distorted corner-sharing HgNa4 tetrahedra. In the NaSn framework, Na is bonded to four equivalent Sn atoms to form distorted corner-sharing NaSn4 tetrahedra. All Na–Sn bond lengths are 3.20 Å. Sn is bonded in a 4-coordinate geometry to four equivalent Na atoms.
