Materials Data on Sr(AlTe2)2 by Materials Project
Sr(AlTe2)2 crystallizes in the tetragonal I422 space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight equivalent Te2- atoms. All Sr–Te bond lengths are 3.55 Å. Al3+ is bonded to four equivalent Te2- atoms to form edge-sharing AlTe4 tetrahedra. All Al–Te bond lengths are 2.65 Å. Te2- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and two equivalent Al3+ atoms.
