The material structure described by Sr4Al6TeO12 crystallizes in the cubic I-43m space group. Sr(1) is bonded to one Te(1) and six equivalent O(1) atoms to form distorted SrTeO6 hexagonal pyramids that share corners with nine equivalent Sr(1)TeO6 hexagonal pyramids and edges with six equivalent Al(1)O4 tetrahedra. Al(1) is bonded to four equivalent O(1) atoms to form AlO4 tetrahedra that share corners with four equivalent Al(1)O4 tetrahedra and edges with four equivalent Sr(1)TeO6 hexagonal pyramids. Te(1) is bonded in a tetrahedral geometry to four equivalent Sr(1) atoms. O(1) is bonded in a 4-coordinate geometry to two equivalent Sr(1) and two equivalent Al(1) atoms. is represented by the CIF card [CIF]
