Materials Data on Al6Cd4SO12 by Materials Project

Abstract

Cd4Al6SO12 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Cd2+ is bonded to one S2- and three equivalent O2- atoms to form distorted CdSO3 tetrahedra that share corners with three equivalent CdSO3 tetrahedra and corners with six equivalent AlO4 tetrahedra. The Cd–S bond length is 2.57 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 CdSO3 tetrahedra and corners with four equivalent AlO4 tetrahedra. All Al–O bond lengths are 1.77 Å. S2- 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.
