Materials Data on Na2TlHg by Materials Project

Abstract

Na2HgTl crystallizes in the cubic F-43m space group. The structure is three-dimensional. there are two inequivalent Na sites. In the first Na site, Na is bonded to four equivalent Tl atoms to form distorted corner-sharing NaTl4 tetrahedra. All Na–Tl bond lengths are 3.28 Å. In the second Na site, Na is bonded to four equivalent Hg atoms to form distorted corner-sharing NaHg4 tetrahedra. All Na–Hg bond lengths are 3.28 Å. Hg is bonded in a body-centered cubic geometry to four equivalent Na and four equivalent Tl atoms. All Hg–Tl bond lengths are 3.28 Å. Tl is bonded in a body-centered cubic geometry to four equivalent Na and four equivalent Hg atoms.
