Na4TeSe is alpha bismuth trifluoride-derived structured and crystallizes in the tetragonal P4/mmm space group. Na(1) is bonded to two equivalent Te(1) and two equivalent Se(1) atoms to form a mixture of corner and edge-sharing NaTe2Se2 tetrahedra. Te(1) is bonded in a body-centered cubic geometry to eight equivalent Na(1) atoms. Se(1) is bonded in a body-centered cubic geometry to eight equivalent Na(1) atoms.
