Materials Data on Sr4Al6SO16 by Materials Project

Sr4Al6O12SO4 crystallizes in the cubic I-43m space group. The structure is three-dimensional and consists of two sulfuric acid molecules and one Sr2Al3O6 framework. In the Sr2Al3O6 framework, Sr2+ is bonded in a distorted trigonal non-coplanar geometry to three equivalent O2- atoms. All Sr–O bond lengths are 2.48 Å. Al3+ is bonded to four equivalent O2- atoms to form corner-sharing AlO4 tetrahedra. All Al–O bond lengths are 1.76 Å. O2- is bonded in a 3-coordinate geometry to one Sr2+ and two equivalent Al3+ atoms.

Materials Data on Sr4Al6SO12 by Materials Project

Sr4Al6SO12 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Sr2+ is bonded in a 4-coordinate geometry to one S2- and six equivalent O2- atoms. The Sr–S bond length is 2.96 Å. There are three shorter (2.48 Å) and three longer (3.13 Å) Sr–O bond lengths. Al3+ is bonded to four equivalent O2- atoms to form corner-sharing AlO4 tetrahedra. All Al–O bond lengths are 1.77 Å. S2- is bonded in a tetrahedral geometry to four equivalent Sr2+ atoms. O2- is bonded in a 3-coordinate geometry to two equivalent Sr2+ and two equivalent Al3+ atoms.
