Sr4Al6O12SO4 crystallizes in the cubic I-43m space group. The structure consists of two sulfuric acid molecules inside a Sr2Al3O6 framework. In the Sr2Al3O6 framework, Sr(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent O(1) atoms. Al(1) is bonded to four equivalent O(1) atoms to form corner-sharing AlO4 tetrahedra. O(1) is bonded in a 3-coordinate geometry to one Sr(1) and two equivalent Al(1) atoms.
