Materials Data on NaAlSe2 by Materials Project
NaAlSe2 crystallizes in the tetragonal I4/mcm space group. The structure is three-dimensional. Na1+ is bonded in a 8-coordinate geometry to eight equivalent Se2- atoms. All Na–Se bond lengths are 3.28 Å. Al3+ is bonded to four equivalent Se2- atoms to form edge-sharing AlSe4 tetrahedra. All Al–Se bond lengths are 2.43 Å. Se2- is bonded in a 2-coordinate geometry to four equivalent Na1+ and two equivalent Al3+ atoms.
