Materials Data on Na4TeSe by Materials Project
Na4TeSe is Fluorite-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Na1+ is bonded to two equivalent Te2- and two equivalent Se2- atoms to form a mixture of edge and corner-sharing NaTe2Se2 tetrahedra. Both Na–Te bond lengths are 3.12 Å. Both Na–Se bond lengths are 3.02 Å. Te2- is bonded in a body-centered cubic geometry to eight equivalent Na1+ atoms. Se2- is bonded in a body-centered cubic geometry to eight equivalent Na1+ atoms.
