The corner-sharing octahedral tilt angles range from 0-8°. There are six inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Sr(1), two equivalent Sr(2), one W(2), and one Cd(2) atom to form distorted face-sharing OSr4CdW octahedra. In the second O site, O(2) is bonded in a distorted linear geometry to two equivalent Sr(1), two equivalent Sr(2), one W(2), and one Cd(2) atom.
