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.
