The material structure described by Sr4WAl6O16 crystallizes in the cubic I-43m space group. Sr(1) is bonded to one O(2) and six equivalent O(1) atoms to form SrO7 hexagonal pyramids that share corners with six equivalent Sr(1)O7 hexagonal pyramids,  a cornercorner with one W(1)O4 tetrahedra, and edges with six equivalent Al(1)O4 tetrahedra. W(1) is bonded to four equivalent O(2) atoms to form WO4 tetrahedra that share corners with four equivalent Sr(1)O7 hexagonal pyramids. Al(1) is bonded to four equivalent O(1) atoms to form AlO4 tetrahedra that share corners with four equivalent Al(1)O4 tetrahedra and edges with four equivalent Sr(1)O7 hexagonal pyramids. There are two inequivalent O sites. In the first O site, O(2) is bonded in a linear geometry to one Sr(1) and one W(1) atom. In the second O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Sr(1) and two equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
