Crystal defects in the h’-WO3 framework. The study has been performed on the bronze recovered directly after aqueous synthesis. a STEM-HAADF micrograph showing in yellow five-membered (WO6)5 rings where one octahedra has been removed from a (WO6)6 wheel, b 30°-rotation of (WO6)6 wheels around the c axis (purple), c antiphase boundaries showing displacement of the structure by a vector ½ [100] along (100) directions (red dashed lines). d STEM-HAADF and e corresponding STEM-ABF images of superimposed (WO6)6 rings rotated by 30° with respect to each other
