Materials Data on Sr4Al6TeO12 by Materials Project
Sr4Al6TeO12 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Sr2+ is bonded to one Te2- and six equivalent O2- atoms to form distorted SrTeO6 hexagonal pyramids that share corners with nine equivalent SrTeO6 hexagonal pyramids and edges with six equivalent AlO4 tetrahedra. The Sr–Te bond length is 3.35 Å. There are three shorter (2.52 Å) and three longer (2.97 Å) Sr–O bond lengths. Al3+ is bonded to four equivalent O2- atoms to form AlO4 tetrahedra that share corners with four equivalent AlO4 tetrahedra and edges with four equivalent SrTeO6 hexagonal pyramids. All Al–O bond lengths are 1.76 Å. Te2- is bonded in a tetrahedral geometry to four equivalent Sr2+ atoms. O2- is bonded in a 2-coordinate geometry to two equivalent Sr2+ and two equivalent Al3+ atoms.
