Materials Data on NaAlTe2 by Materials Project
NaAlTe2 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. Na1+ is bonded in a 8-coordinate geometry to eight equivalent Te2- atoms. All Na–Te bond lengths are 3.52 Å. Al3+ is bonded to four equivalent Te2- atoms to form edge-sharing AlTe4 tetrahedra. All Al–Te bond lengths are 2.67 Å. Te2- is bonded in a 6-coordinate geometry to four equivalent Na1+ and two equivalent Al3+ atoms.
