Figure 3
Precession electron-diffraction patterns of (a)–(c) ∊₆ and (d)–(f) ∊₁₆, and (g)–(i) the simulated precession electron-diffraction patterns from the derived structure model of ∊₁₆. The kinematical simulation conditions are: voltage 200 kV, precession angle 1.1°, and crystal thicknesses (g) 400 Å, (h) 500 Å and (i) 400 Å. The intensity distributions in reciprocal space are similar for ∊₆ and ∊₁₆. The corresponding reflections have the same h and k, but l(∊₁₆) ≃ τ² l(∊₆), such that the very strong reflection (006) in ∊₆ corresponds to (00 $[_{\prime} ]$ 16) in ∊₁₆.
