Materials Data on Al6Cd4TeO12 by Materials Project
Cd4Al6TeO12 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Cd2+ is bonded to one Te2- and three equivalent O2- atoms to form distorted CdTeO3 tetrahedra that share corners with three equivalent CdTeO3 tetrahedra and corners with six equivalent AlO4 tetrahedra. The Cd–Te bond length is 2.82 Å. All Cd–O bond lengths are 2.24 Å. Al3+ is bonded to four equivalent O2- atoms to form AlO4 tetrahedra that share corners with four equivalent CdTeO3 tetrahedra and corners with four equivalent AlO4 tetrahedra. All Al–O bond lengths are 1.77 Å. Te2- is bonded in a tetrahedral geometry to four equivalent Cd2+ atoms. O2- is bonded in a trigonal planar geometry to one Cd2+ and two equivalent Al3+ atoms.
