The crystal structure described by Ca4Al6TeO12 crystallizes in the cubic I-43m space group. Ca(1) is bonded in a distorted trigonal non-coplanar geometry to one Te(1) and three equivalent O(1) atoms. Al(1) is bonded to four equivalent O(1) atoms to form corner-sharing AlO4 tetrahedra. Te(1) is bonded in a tetrahedral geometry to four equivalent Ca(1) atoms. O(1) is bonded in a distorted trigonal planar geometry to one Ca(1) and two equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
